Abstract

Grubbs’ ruthenium-based catalysts (1 and 2) have demonstrated remarkable efficiency in olefin metathesis over the past ten years. [1] However, non-metathetic applications ­appeared very recently that deserve special attention and broaden the synthetic utility of Grubbs’ catalysts. [2] The complexes were shown to catalyze the Kharasch addition, the removal of allyl groups from amines, the atom-transfer radical polymerization, [3] the hydrogenation of olefins, the transfer hydrogenation of ketones, [4] the dehydro­genative oxidation of alcohols, the dehydrogenative condensation of alcohols, isomerization, hydrosilylation of alkynes, cycloaddition and the hydro-silylation of carbonyls. [5] The aim of this article is to give some examples of these advances, with special focus on practical concerns.
