An oxidation system consisting of methyltrioxorhenium and H 2 O 2 catalyzes the cleavage of CC-double bonds. By varying the reaction conditions, it is possible to generate either the aldehyde or the carboxylic acid in reasonable-to-excellent yields a

Two N-heterocyclic carbene ligands at once may be one too many, at least if you intend to have highly active ruthenium catalysts for olefin metathesis. Density functional calculations recommend the replacement of the second carbene ligand in the succ

Ruthenium-based catalysts for olefin metathesis have attained enormous attention during the past years. Recently we have shown that the application of N -heterocyclic carbenes extends and complements the ubiquitous phosphanes. We now report on new me
