Abstract

Oxidation potentials of acylsilanes were found to be much less positive than those of ketones an. d aldehydes. The effect of silicon is attributed to the rise of the HOMO level by the interaction between the C-Si u orbital and the nonbonding p orbital of the carbonyl oxygen which in turn favors the electron transfer. Preparative electrochemical oxidation of acylsilanes proceeded smoothly, giving rise to facile cleavage of the C-Si bond and the ...
