The deoxygenation of tosylated arenes catalyzed by a palladium complex is described. This method represents one of the first general examples of reductive C–O bond cleavage of aryl tosylates via palladium catalysis. By simply employing isopropanol

This study describes the efficacy of benzimidazolyl phosphine ligands, which are easily synthesized from inexpensive and commercially available o-phenylenediamine, 2-bormobenzoic acid, and chlorophosphines, in the Buchwald-Hartwig amination of aryl c

A dicationic dichloro-bipyridine-ruthenium complex shows very high catalytic activity in redox isomerization of allylic alcohols but a relatively low one in transfer hydrogenation of ketones; surprisingly, the analogous dimethyl-bipyridine-ruthenium

The first general examples of palladium-catalyzed direct and selective oxidative C3-acetoxylation of indoles are presented. The mild reaction conditions (70 °C and with weak base, KOAc) in this indole C-H-acetoxylation are notable.

An X-ray crystallographic study showed that it is more appropriate to describe the complexes TpRu(PPh 3 )"H 2 SiR 3 " as TpRu(PPh 3 )(η 3 -HSiR 3 H), a static structure containing H···Si···H bonding rather than a highly fluxional pair of σ-si

The first general examples of palladium-catalyzed Suzuki-type cross-coupling of aryl and heteroaryl mesylates with potassium aryl and heteroaryltrifluoroborates are presented. In addition to biaryl couplings, the cross-coupling reactions of aryl mesy
