Nanosecond photoreduction of cytochrome P450cam by channel-specific Ru-diimine electron tunneling wires

We report the synthesis and characterization of Ru-diimine complexes designed to bind to cytochrome P450cam (CYP101). The sensitizer core has the structure [Ru(L2)L’]2+, where L’ is a perfluorinated biphenyl bridge (F8bp) connecting 4,4?-dimethylbipyridine to an enzyme substrate (adamantane, F8bp-Ad), a heme ligand (imidazole, F8bp-lm), or F (F9bp). The electron-transfer (ET) driving force (-deltaG) is varied by replacing the ancillary 2,2? -bipyridine ligands with 4,4?,5,5?-tetramethylbipyridine (tmRu). The four complexes all bind P450cam tightly: Ru-F8bp-Ad (1, K d = 0.077 muM); Ru-F8bp-lm (2, Kd = 3.7 muM); tmRu-F9bp (3, Kd = 2.1 muM); and tmRu-F 8bp-lm (4, Kd = 0.48 muM). Binding is predominantly driven by hydrophobic interactions between the Ru-diimine wires and the substrate access channel. With Ru-F8bp wires, redox reactions can be triggered on the nanosecond time scale. Ru-wire 2, which ligates the heme iron, shows a small amount of transient heme photoreduction (ca. 30%), whereas the transient photoreduction yield for 4 is 76%. Forward ET with 4 occurs in roughly 40 ns (kf = 2.8 ¡Á 107 s-1), and back ET (FeII ? RuIII, kb ? 1.7 ¡Á 108 s-1) is near the coupling-limited rate (k max). Direct photoreduction was not observed for 1 or 3. The large variation in ET rates among the Ru-diimine:P450 conjugates strongly supports a through-bond model of Ru-heme electronic coupling.

Synthesis, molecular structure and evaluation of new organometallic ruthenium anticancer agents

A number of new ruthenium compounds have been synthesised, isolated and characterised, which exhibit excellent cytotoxicity against a number of different human tumour cell lines including a defined cisplatin resistant cell line and colon cancer cell lines. Addition of hydrophobic groups to the ruthenium molecules has a positive effect on the cytotoxicity values. Evidence is provided that, after incubation of a ruthenium compound with a 46 mer oligonucleotide duplex and subsequent nuclease treatment, ruthenium is bound to a guanine residue.

Indolizinones as synthetic scaffolds: Fundamental reactivity and the relay of stereochemical information

Indolizinones are under-explored N-heterocycles that react with exquisite chemo- and stereoselectivity. An exploration of the fundamental reactivity of these azabicycles demonstrates the potential to relay stereochemical information from the ring-fusion to newly formed stereocenters on the bicyclic core. The indolizinone diene undergoes selective hydrogenation and readily participates in Diels-Alder cycloadditions as well as ene reactions. The vinylogous amide embedded in the five-membered ring is resistant to reaction when the diene is in place. However, removal of the diene allows for diastereoselective hydrogenation of, and 1,4-additions to, the vinylogous amide. These fundamental reactions with indolizinones have provided a structurally diverse array of products that hold promise in the context of natural product synthesis.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 246047-72-3 is helpful to your research., Synthetic Route of 246047-72-3

Switched stereocontrol in Grubbs – Hoveyda complex catalyzed ROMP utilizing proton-switched NHC ligands

Grubbs-Hoveyda and Grubbs III type complexes with ferrocenyl- or -NEt 2-substituted NHC ligands were synthesized according to standard procedures. The electron donation of the NHC ligands in the respective ruthenium complexes can be modulated by oxidation of the ferrocenyl moiety or by protonation of the amino group. The neutral and the respective cationic (oxidized or protonated) ruthenium complexes were tested in the ROMP of norbornene. The change in the electron donation of the NHC ligands upon protonation leads to a significant change in the double-bond geometry (from E/Z ratio = 0.78 to E/Z = 1.04) and in the microstructure of the resulting polynorbornene. Consequently, addition of acid and protonation of the living catalyst attached to the polymer chain during the polymerization reaction allows fine-tuning the E/Z ratio of the resulting polynorbornene.

Bis(alkynyl), metallacyclopentadiene, and diphenylbutadiyne complexes of ruthenium

Heating diphenylbutadiyne with [Ru(CO)2(PPh3) 3] or [Ru(CO)3(PPh3)2] in toluene under reflux provides respectively the ruthenacyclopentadiene [Ru{kappa2-CR=CPhCPh=CR}(CO)2(PPh3) 2] (R = C?CPh) or the cyclopentadienone complex [Ru{eta4-O=CC4Ph2R2}(CO) 2(PPh3)], the latter via [2 + 2 + 1] alkyne and CO cyclization. The bis(alkynyl) complex cis,cis,trans-[Ru(C?CPh) 2(CO)2(PPh3)2] is not formed in either of these reactions but is the product of the reaction of [RuCl 2(CO)2(PPh3)2] with LiC?CPh or of cis,-mer-[Ru(C?CPh)2(CO)(PPh3)3] with CO. Although the bis(alkynyl) complex does not undergo reductive elimination to provide the diyne complex, thermolysis of cis,cis,trans-[Ru(C?CPh) (HgC?CPh)(CO)2-(PPh3)2] (obtained from [Ru(CO)2(PPh3)3] and [Hg(C?CPh) 2]) provides a noninterconvertible 1:1 mixture of cis,cis,trans-[Ru(C?CPh)2(CO)2(PPh3) 2] and [Ru(eta-PhC?CC?CPh)(CO)2(PPh 3)2].

Stabilization of a kinetically favored nanostructure: Surface ROMP of self-assembled conductive nanocoils from a norbornene-appended hexa-peri-hexabenzocoronene

Newly designed norbornene-appended hexabenzocoronene 1 self-assembles, upon diffusion of an Et2O vapor into its CH2Cl2 solution, to form either graphitic nanocoils or nanotubes, depending on the self-assembling conditions. The coiled assembly, selectively formed at 15 C, is a kinetic intermediate for the tubular assembly and transforms into nanotubes on standing at 25 C. However, post-ring-opening metathesis polymerization of the norbornene pendants of 1 enhances the thermal stability of the coiled assembly as well as the tubular one and disables a thermodynamic coil-to-tube transition. The polymerized nanocoils show an electroconductivity of 1 ¡Á 10-4 S cm-1 upon doping with I2, while the nonpolymerized nanocoils are disrupted upon being doped.

Tetradentate selenium ligand as a building block for homodinuclear complexes of Pd(II) and Ru(II) having seven membered rings or bis-pincer coordination mode: High catalytic activity of Pd-complexes for Heck reaction

1,2,4,5-Tetrakis(phenyselenomethyl)benzene (L) has been synthesized by reaction of in situ generated PhSe- with 1,2,4,5- tetrakis(bromomethyl)benzene in N2 atmosphere. Its first bimetallic complexes and a bis-pincer complex having compositions [(eta3- C3H5)2Pd2(L)][ClO4] 2 (1) [Pd2(C5H5N) 2(L)][BF4]2 (2) and [(eta6-C 6H6)2Ru2(L)Cl2][PF 6]2 (3) have been synthesized by reacting L with [Pd(eta3-C3H5)Cl]2, [Pd(CH 3CN)4][BF4]2 and [(eta6-C6H6)2RuCl 2]2 respectively. The structures of ligand L and its all three complexes have been determined by X-ray crystallography. In 1 and 3, ligand L forms with two organometallic species seven membered chelate rings whereas in 2 it ligates in a bis-pincer coordination mode. The geometry around Pd in 1 or 2 is close to square planar whereas in 3, Ru has pseudo-octahedral half sandwich “Piano-Stool” geometry. The Pd-Se bond distances are in the ranges 2.4004(9)-2.4627(14) A and follow the order 1 > 2, whereas Ru-Se bond lengths are between 2.4945(16) and 2.5157(17) A. The 1 and 2 have been found efficient catalysts for Heck reaction of aryl halides with styrene and methyl acrylate. The 2 is superior to 1. The TON and TOF values (per Pd) are up to ? 47500 and ?2639 h-1 respectively. The Royal Society of Chemistry 2010.

Half-sandwich ruthenium(ii) complexes with tethered arene-phosphinite ligands: Synthesis, structure and application in catalytic cross dehydrogenative coupling reactions of silanes and alcohols

The preparation of the tethered arene-ruthenium(ii) complexes [RuCl2{eta6:kappa1(P)-C6H5(CH2)nOPR2}] (R = Ph, n = 1 (9a), 2 (9b), 3 (9c); R = iPr, n = 1 (10a), 2 (10b), 3 (10c)) from the corresponding phosphinite ligands R2PO(CH2)nPh (R = Ph, n = 1 (1a), 2 (1b), 3 (1c); R = iPr, n = 1 (2a), 2 (2b), 3 (2c)) is presented. Thus, in a first step, the treatment at room temperature of tetrahydrofuran solutions of dimers [{RuCl(mu-Cl)(eta6-arene)}2] (arene = p-cymene (3), benzene (4)) with 1-2a-c led to the clean formation of the corresponding mononuclear derivatives [RuCl2(eta6-p-cymene){R2PO(CH2)nPh}] (5-6a-c) and [RuCl2(eta6-benzene){R2PO(CH2)nPh}] (7-8a-c), which were isolated in 66-99% yield. The subsequent heating of 1,2-dichloroethane solutions of these compounds at 120 C allowed the exchange of the coordinated arene. The substitution process proceeded faster with the benzene derivatives 7-8a-c, from which complexes 9-10a-c were generated in 61-82% yield after 0.5-10 h of heating. The molecular structures of [RuCl2(eta6-p-cymene){iPr2PO(CH2)3Ph}] (6c) and [RuCl2{eta6:kappa1(P)-C6H5(CH2)nOPiPr2}] (n = 1 (10a), 2 (10b), 3 (10c)) were unequivocally confirmed by X-ray diffraction methods. In addition, complexes [RuCl2{eta6:kappa1(P)-C6H5(CH2)nOPR2}] (9-10a-c) proved to be active catalysts for the dehydrogenative coupling of hydrosilanes and alcohols under mild conditions (r.t.). The best results were obtained with [RuCl2{eta6:kappa1(P)-C6H5(CH2)3OPiPr2}] (10c), which reached TOF and TON values up to 117 600 h-1 and 57 000, respectively.
