Reactions of the Lithiated Diphosphine tBu2P?P(SiMe3)Li with [(eta6-C6H6)RuCl2]2in the Presence of Tertiary Phosphines

tBu2P?P(SiMe3)Li reacted with [(eta6-C6H6)RuCl2]2at ?40 C in the presence of PR3(PR3= PEt3, PEt2Ph, PEtPh2) by the nucleophilic addition of the tBu2P?P(SiMe3) moiety to the benzene ring to yield solely the complexes [(R3P)2Ru(Cl){eta5-C6H6(Me3SiP?PtBu2)}] (1). These products decomposed slowly at ambient temperature to yield benzene, Ru clusters, and small amounts of the dinuclear ruthenium complexes [{(R3P)2Ru}2(mu,eta2:2-P2)2Ru(PR3)2] (Ru?Ru) (6). Single-crystal X-ray diffraction studies of [(PhEt2P)2Ru(Cl){eta5-C6H6(Me3SiP?PtBu2)}] (1b) and [(Ph2EtP)2Ru(Cl){eta5-C6H6(Me3SiP?PtBu2)}] (1c) revealed that the addition of the tBu2P?P(SiMe3) group occurred through an exo pathway. Complex 6a (R = Et) displays a planar rectangular P4system consisting of two P2units and a Ru?Ru distance that lies in the range of a single bond.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 37366-09-9, you can also check out more blogs about37366-09-9

Kinetic selectivity of olefin metathesis catalysts bearing cyclic (alkyl)(amino)carbenes

The evaluation of ruthenium olefin metathesis catalysts 4-6 bearing cyclic (alkyl)(amino)carbenes (CAACs) in the cross-metathesis of cis-1,4-diacetoxy-2- butene (7) with allylbenzene (8) and the ethenolysis of methyl oleate (11) is reported. Relative to most NHC-substituted complexes, CAAC-substituted catalysts exhibit lower E/Z ratios (3:1 at 70% conversion) in the cross-metathesis of 7 and 8. Additionally, complexes 4-6 demonstrate good selectivity for the formation of terminal olefins versus internal olefins in the ethenolysis of 11. Indeed, complex 6 achieved 35 000 TONs, the highest recorded to date. CAAC-substituted complexes exhibit markedly different kinetic selectivity than most NHC-substituted complexes.

New ruthenium(II)-letrozole complexes as anticancer therapeutics

Novel ruthenium-letrozole complexes have been prepared, and cell viability of two human cancer cell types (breast and glioblastoma) was determined. Some ruthenium compounds are known for their cytotoxicity to cancer cells, whereas letrozole is an aromatase inhibitor administered after surgery to post-menopausal women with hormonally responsive breast cancer. A significant in vitro activity was established for complex 5¡¤Let against breast cancer MCF-7 cells and significantly lower activity against glioblastoma U251N cells. The activity of 5¡¤Let was even higher than that of 4, a compound analogous to the well-known drug RAPTA-C. Results from the combination of 5¡¤Let (or 4) with 3-methyladenine (3-MA) or with curcumin, respectively, revealed that the resultant cancer cell death likely involves 5¡¤Let-induced autophagy.

A Ruthenium(II) Complex as a Luminescent Probe for DNA Mismatches and Abasic Sites

[Ru(bpy)2(BNIQ)]2+ (BNIQ = Benzo[c][1,7]naphthyridine-1-isoquinoline), which incorporates the sterically expansive BNIQ ligand, is a highly selective luminescent probe for DNA mismatches and abasic sites, possessing a 500-fold higher binding affinity toward these destabilized regions relative to well-matched base pairs. As a result of this higher binding affinity, the complex exhibits an enhanced steady-state emission in the presence of DNA duplexes containing a single base mismatch or abasic site compared to fully well-matched DNA. Luminescence quenching experiments with Cu(phen)22+ and [Fe(CN)6]3- implicate binding of the complex to a mismatch from the minor groove via metalloinsertion. The emission response of the complex to different single base mismatches, binding preferentially to the more destabilized mismatches, is also consistent with binding by metalloinsertion. This work shows that high selectivity toward destabilized regions in duplex DNA can be achieved through the rational design of a complex with a sterically expansive aromatic ligand.

Reactions of Ruthenium Complexes Containing Pentatetraenylidene Ligand

Two ruthenium acetylide complexes [Ru]?C?C?C?C?C(OR)(C3H5)2 (2, R=H and 2 a, R=CH3; [Ru]=Cp(PPh3)2Ru) each with two cyclopropyl rings were synthesized from TMS?C?C?C?C?C(OH)(C3H5)2 (1; TMS=trimethylsilyl). Treatments of 2 and 2 a with allyl halide in the presence of KPF6 afforded the vinylidene complexes 3 and 3 a, respectively. When NH4PF6 was used, instead of KPF6, additional ring-opening reaction took place on one of the three-membered ring. Treatment of [Ru]Cl with 1,3-butadiyne (6), bearing an epoxide ring, afforded acetylide complex 7 with a furyl ring. Treatment of 2 a with Ph3CPF6 presumably afforded pentatetraenylidene complex {[Ru]=C=C=C=C=C(C3H5)2}[PF6] (10), which was not isolated. Additions of various alcohols in a solution of 10 generated a number of disubstituted allenylidene complexes {[Ru]=C=C=C(OR)?C=C(C3H5)2}[PF6] (11). Treatment of 11 with K2CO3 afforded the acetylide complex 12 bearing a carbonyl group, characterized by single X-ray diffraction analysis. Addition of a primary amine to 10 caused cleavage of the farthermost C=C bond and several allenylidene complexes {[Ru]=C=C=C(Me)(NHR)}[PF6] (18) were isolated.

Reactions of ‘GaI’ with organometallic transition metal halides

Two approaches towards the synthesis of phosphine ligated half-sandwich complexes [(etax-CxHx)M(PR3)2GaI2]n containing diiodogallyl ligands have been investigated. Insertion of ‘GaI’ into the Mo-I bond of (eta7-C7H7)Mo(CO)2I has been shown to yield the crystallographically characterized dimeric complex [(eta7-C7H7)Mo(CO)2GaI2]2 (2). Attempts to substitute the carbonyl ligands by the phosphine ligand dppe [dppe = bis(diphenylphosphino)ethane] have been shown instead to yield the sparingly soluble complex [(eta7-C7H7)Mo(CO)2GaI2]2(mu-dppe) (3) in which the phosphine bridges two [(eta7-C7H7)Mo(CO)2GaI2] units via a pair of P ? Ga donor/acceptor bonds. By contrast, attempts to insert ‘GaI’ directly into the metal-halogen bond of phosphine ligated complexes such as (eta5-C5H5)Ru(PPh3)2Cl or (eta5-C5H5)Ru(dppe)Cl have been shown to result in the formation of the tetraiodogallate species(eta5-C5H5)Ru(PPh3)2(mu-I)GaI3 (5) and [(eta5-C5H5)Ru(dppe)]+[GaI4]- (7).

Oxidation of primary alcohols to aldehydes with oxygen catalysed by tetra-n-propylammonium perruthenate

The liquid-phase oxidation of a series of saturated and unsaturated non-allylic alcohols to aldehydes with oxygen or air catalysed by tetra-n-propylammonium perruthenate (TPAP, represented as [(n-Pr)4N]RuO4) at 80-110 C is shown to proceed with selectivities of 72-91% at 55-80% alcohol conversion. The unsaturated alcohols, such as 9-decenol, 9-octadecenol and beta-citronellol, give the corresponding unsaturated aldehydes without competing double bond attack. The time course of oxidation indicates a complex reaction mechanism. The results on oxidation of a test alcohol, t-Bu(Ph)CHOH, suggest that one-electron processes do not play an important role in the TPAP-catalysed aerobic oxidation of alcohols.

Regio- and Diastereoselective Functionalization of 3-Amino-hexahydrooxazoninones

The regio- and diastereoselectivity of transformations of nine-membered lactams with a Z double bond in the cyclic tether towards building blocks for medicinal chemistry was evaluated. To this end, 3-aminohexahydrooxazoninones were synthesized using a standard ring-closing metathesis (RCM) approach of easily available O,N-bisallylated serine derivatives. The obtained Z double bond in the medium sized lactam was used as a handle to evaluate the stereoselectivity of electrophile induced transformations. It was shown that dibromination and electrophilic activation by NBS followed by attack of O-nucleophiles proceeded in a diastereoselective manner. Cyclization of obtained bromohydrins and face-selective epoxidation gave access to both diastereomers of the epoxidized lactams. Finally, a Heck-reaction of a bromobenzyl moiety at the lactam N-atom with the Z-double bond resulted in the diastereoselective formation of bicyclic bridged nine-membered lactams.
