Oxidation of organometallic reagents, 1 especially organoborane2 and organosilicon3 compounds, is a methodology of great importance in organic synthesis for the preparation of alcohols. In general, the oxidation of a carbon-metal σ-bond does not provide carbonyl compounds (except from oxidation of vinylmetals). Knochel pioneered the oxidation of dimetallic compounds with oxygen to yield ketones (Scheme 1). 4 Since then, however, ...
