Observation of cascade f ? d ? f energy transfer in sensitizing near-infrared (NIR) lanthanide complexes containing the Ru(ii) polypyridine metalloligand

Distinguishable d ? f or f ? d energy transfer processes depending on lanthanide ions are observed in isomorphous d-f heterometallic complexes containing the Ru(ii) metalloligand (LRu), which lead to sensitized NIR emission (for Nd3+ and Yb3+) or enhanced red emission of LRu (for Eu3+ and Tb3+), and represent the first eye-detectable evidence of f ? d energy transfer processes in Ln-Ru bimetallic complexes. Based on the systematic luminescence and decay lifetime study, cascade f ? d ? f energy transfer has been proposed in Ln1-Ru-Ln2 trimetallic systems for improved NIR sensitization.

CATALYSIS OF HYDROSILYLATION. VII. CATALYSIS OF HYDROSILYLATION OF C=C BONDS BY RUTHENIUM PHOSPHINE COMPLEXES

A full account of the catalysis of hydrosilylation of the C=C bond in olefins, their derivatives with functional groups as well as in vinyl-trisubstituted silanes by ruthenium(II) and ruthenium(III) phosphine precursors is given.The ruthenium complexes are far more efficient catalysts for the hydrosilylation of 1-alkenes and vinyl-substituted silanes than for the substituted olefins and unsaturated esters.General features characterizing all hydrosilylation reactions catalyzed by the above catalysts are as follows: the reaction proceeds with alkoxy-substituted silanes(also with vinylsilanes) in the absence of solvent, and is enhanced (for RuII and olefins occurs exclusively) in the presence of molecular oxygen.Two general mechanisms are proposed for hydrosilylation of olefins and of vinylsilanes, respectively, which account for most of the experimental observations.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 10049-08-8, help many people in the next few years., Related Products of 10049-08-8

Fast olefin metathesis: Synthesis of 2-aryloxy-substituted Hoveyda-type complexes and application in ring-closing metathesis

Four 1-(4-R-phenoxy)-2-ethenylbenzenes (R=NMe2, H, Cl, NO 2) 4a, 4b, 4c and 4d were reacted with the ruthenium complexes [RuCl2(NHC)(3-phenylindenylidene)(py)] in the presence of a protic resin to result in the formation of the respective Hoveyda-type complexes 5a-d {NHC=SIMes [1,3-bis(2,4,6-trimethylphenylimidazolin)-2-ylidene]} and 6a-d {NHC=SIPr [1,3-bis(2,6-diisopropylphenylimidazolin)-2-ylidene]} in 66-84% yield. The lower steric bulk and the decreased donation of the diaryl ether oxygen atoms in complexes 5 and 6 led to rapidly initiating precatalysts. The Ru(II/III) redox potentials of complexes 6 were determined (6a-d: DeltaE=0.89-1.08 V). In the crystal structure of 5b two independent molecules were observed in the unit cell, displaying Ru-O distances of 226.6(4) and 230.5(3) pm. The catalytic performance of complexes 5 and 6 in various ring-closing metathesis (RCM) reactions was studied. Catalyst loadings of between 15-200 ppm are sufficient for the formation of >90% yield of the respective cyclic products. Complex 6b catalyzes the formation of N-protected 2,5-dihydropyrroles with up to TON 64,000 and TOF 256,000 h-1, of the N-protected 1,2,3,6- tetrahydropyridines with up to TON 18,200 and TOF 73,000 h-1 and of the N-protected 2,3,6,7-tetrahydroazepines with up to TON 8,100 and TOF 32,000 h-1 with yields ranging between 77 and 96%.

Method for Making Industrial Chemicals

A process for producing industrially important chemicals from renewable resources is disclosed.

In one embodiment of the process 1-octene, along with methyl-9-decenoate and butadiene, is produced from linoleic acid via an enzymemediated isomerization reaction, followed by a metathesis reaction with ethylene. Linoleic acid can be isolated from vegetable oils, such as soybean oil.

Photophysics of Re(I) and Ru(II) diimine complexes covalently linked to pyrene: Contributions from intra-ligand charge transfer states

The photophysical properties of Ru(II) and Re(I) polypyridyl complexes including a bis-bipyridyl pyrene ligand are presented. The complexes {[(bpy)2Ru]2bpb}4+ and [(CO)3ReCl(bpb)] = 2,2?-bipyridine, bpb = 1,6-bis-(4(2,2?-bipyrid-yl)-pyrene) were designed with the intent of examining intramolecular energy migration between MLCT states localized on the metal complexes and pyrene-localized 3(pi-pi*) states. Absorption spectroscopy of both complexes containing the bpb ligand reveals that in addition to the MLCT and the pyrene-centered 1(pi-pi*) transitions, a new absorption band is observed near 400 nm for both complexes. Absorption spectral data for the Re(I) complex strongly suggest the presence of a pyrene(pi) to bpy(pi*) intraligand charge transfer (ILCT) transition. Emission spectra at room temperature and at 77 K are almost identical for the Ru(II) and Re(I) complexes containing the bpb ligand. The 3MLCT emission of related bipyridyl compounds lacking the pyrene is observed at higher energy than for the pyrene-containing complexes, {[(bpy)2Ru]2bpb}4+ and [(CO3ReCl(bpb)]. The Ru(II) complex emits at room temperature with a remarkably long lifetime (130 mus in degassed DMSO). This emission is also strongly sensitive to oxygen and is almost entirely quenched in an aerated solution. In addition, excited-state absorption spectra exhibit features not consistent with 3MLCT or 3(pi-pi*) states of the parent chromophores. The combined characteristics suggest the emission arises from either 3(pi-pi*) or 3ILCT states or a state with mixed parentage.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C20H16Cl2N4Ru, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 15746-57-3, in my other articles.
