Transient nonlinear optics of organometallic fullerene: Research on iron(III) and ruthenium(III) derivatives of C60

We synthesized and investigated ultrafast third-order optical response of iron(III) (Fe(III)) and ruthenium(III) (Ru(III)) coordinated fullerene derivatives, which were based on our former reported C60(NH2CN)5 series, at 830 nm. The Fe(III), which is electron deficient and blocks the intramolecular charge-transfer process, reduces the optical nonlinearity of the complexes. However, Ru(III), even it is also electron deficient, enhanced the optical nonlinearity for an order of magnitude. By analyzing the infrared spectrum, a possible effect of linked multi-fullerene molecule system is supposed.

Cationic ruthenium alkylidene catalysts bearing phosphine ligands

The discovery of highly active catalysts and the success of ionic liquid immobilized systems have accelerated attention to a new class of cationic metathesis catalysts. We herein report the facile syntheses of cationic ruthenium catalysts bearing bulky phosphine ligands. Simple ligand exchange using silver(i) salts of non-coordinating or weakly coordinating anions provided either PPh3 or chelating Ph2P(CH2)nPPh2 (n = 2 or 3) ligated cationic catalysts. The structures of these newly reported catalysts feature unique geometries caused by ligation of the bulky phosphine ligands. Their activities and selectivities in standard metathesis reactions were also investigated. These cationic ruthenium alkylidene catalysts reported here showed moderate activity and very similar stereoselectivity when compared to the second generation ruthenium dichloride catalyst in ring-closing metathesis, cross metathesis, and ring-opening metathesis polymerization assays.

Facile synthesis of effcient and selective ruthenium olefin metathesis catalysts with sulfonate and phosphate ligands

A series of novel, air-stable ruthenium NHC catalysts with sulfonate and phosphate anions have been prepared easily in one pot at high yields using commercially available precursors. The catalysts were found to be effective for ring-opening metathesis polymerization, ring-closing metathesis, and cross-metathesis. The catalysts showed higher cis-selectivity in olefin cross-metathesis reactions as compared to earlier known ruthenium-based olefin metathesis catalysts, with allylbenzene and cis-1,4-diacetoxybutene as substrates.

Ring-closing metathesis reactions of terminal alkene-derived cyclic phosphazenes

The first examples of ring-closing metathesis (RCM) reactions of a series of terminal alkene-derived cyclic phosphazenes have been carried out. The tetrakis-, hexakis-, and octakis(allyloxy)cyclophosphazenes (NPPh 2)(NP(OCH2CH = CH2)2)2 (1), N3P3(OCH2CH = CH2)6 (2), and N4P4(OCH2CH = CH2) 8 (3) and the tetrakis(allyloxy)-S-phenylthionylphosphazene (NS(O)Ph)[NP(OCH2CH = CH2)2]2 (4) were prepared by the reactions of CH2 = CHCH2ONa with the cyclophosphazenes (NPPh2)(NPCl2)2, N 3P3Cl6, and N4P4Cl 8 and the S-phenylthionylphosphazene (NS(O)Ph)(NPCl2) 2. The reactions of 1-4 with Grubbs first-generation olefin metathesis catalyst Cl2Ru = CHPh(PCy3)2 resulted in the selective formation of seven-membered di-, tri-, and tetraspirocyclic phosphazene compounds (NPPh2)[NP(OCH2CH = CHCH2O)]2 (5), N3P3(OCH 2CH = CHCH2O)3 (6), and N4P 4(OCH2CH = CHCH2O)4 (7) and the dispirocyclic S-phenylthionylphosphazene compound (NS(O)Ph)[NP(OCH2CH = CHCH2O)]2 (8). X-ray structural studies of 5-8 indicated that the double bond of the spiro-substituted cycloalkene units is in the cis orientation in these compounds. In contrast to the reactions of 1-4, RCM reactions of the homoallyloxy-derived cyclophosphazene and thionylphosphazene (NPPh2)[NP(OCH2CH2CH = CH2) 2]2 (9) and (NS(O)Ph)[NP(OCH2CH2CH = CH2)2]2 (10) with the same catalyst resulted in the formation of 11-membered diansa compounds NPPh2[NP(OCH 2CH2CH = CHCH2CH2O)]2 (11) and (NS(O)Ph)[NP(OCH2CH2CH = CHCH2CH 2O)]2 (13) and the intermolecular doubly bridged ansa-dibino-ansa compounds 12 and 14. The X-ray structural studies of compounds 11 and 13 indicated that the double bonds of the ansa-substituted cycloalkene units are in the trans orientation in these compounds. The geminal bis(homoallyloxy)tetraphenylcyclotriphosphazene [NPPh2] 2[NP(OCH2CH2CH = CH2)2] (15) upon RCM with Grubbs first- and second-generation catalysts gave the spirocyclic product [NPPh2]2[NP(OCH2CH 2CH = CHCH2CH2O)] (16) along with the geminal dibino-substituted dimeric compound [NPPh2]2[NP(OCH 2CH2CH = CHCH2CH2O) 2PN][NPPh2]2 (17) as the major product. The dibino compound 17, upon reaction with the Grubbs second-generation catalyst, was found to undergo a unique ring-opening metathesis reaction, opening up the bino bridges and partially converting to the spirocyclic compound 16.

Rate enhancement by ethylene in the ru-catalyzed ring-closing metathesis of enynes: Evidence for an “ene-then-yne” pathway that diverts through a second catalytic cycle

Diastereomeric > chelate complexes (where R=CH3, cyclo-C6H11, or C6H5) from in nearly equimolar amounts in the displacement reaction of triphenylphosphine form .The diastereomers were separated by fractional crystallization.Diastereomeric composition at the equilibrium showed a low asymmetric induction (28-41percent) by the optically active diphosphine ligand on the chiral ruthenium atom.The absolute configuration at the ruthenium atom has little influence on the chiroptical properties of the complexes, which appear to be dominated, at least in the visible region, by the chiral conformation of the chelate ligand.The crystal structure of the title diastereomer, <(S)RuCl(eta5-C5H5)-<(R)Ph2PCH(Me)CH2PPh2>>, has been investigated.It is monoclinic, space group P21, with a=9.688(3), b=15.037(4), c=10.556(2) Angstroem, beta=113.54(2)deg, and Z=2.The structure was solved by Patterson and Fourier methods, and refined by least squares on the basis of 2 000 significant counter data, to a final R value of 0.042.The complex shows a distored lambda conformation of the diphosphine ligand in the chelate five-membered ring, in the solid state.The Ru-Cl and Ru-P interactions are 2.444(2) and 2.277 Angstroem (mean value), respectively.

Synthesis of panchromatic Ru(II) thienyl-dipyrrin complexes and evaluation of their light-harvesting capacity

Ru(II) complexes with 5-(3-thienyl)-4,6-dipyrrin (3-TDP), containing 2,2?-bipyridine (bpy) or 4,4?-bis(methoxycarbonyl)-2,2?- bipyridine (dcmb) as coligands, have been prepared and extensively characterized. Crystal structure determination of [Ru(bpy)2(3-TDP)] PF6 (1a) and [Ru(bpy)(3-TDP)2] (2) reveals that the 3-thienyl substituent is rotated with respect to the plane of the dipyrrinato moiety. These complexes, as well as [Ru(dcmb)2(3-TDP)]PF6 (1b), act as panchromatic light absorbers in the visible range, with two strong absorption bands observable in each case. A comparison to known Ru(II) complexes and quantum-chemical calculations at the density functional theory (DFT) level indicate that the lower-energy band is due to metal-to-ligand charge transfer (MLCT) excitation, although the frontier occupied metal-based molecular orbitals (MOs) contain significant contributions from the 3-TDP moiety. The higher energy band is assigned to the pi-pi* transition of the 3-TDP ligand. Each complex exhibits an easily accessible one-electron oxidation. According to DFT calculations and spectroelectrochemical experiments, the first oxidation takes place at the RuII center in 1a, but is shifted to the 3-TDP ligand in 1b. An analysis of MO energy diagrams suggests that complex 1b has potential to be used for light harvesting in the dye-sensitized (Graetzel) solar cell.
