1,3-Disubstituted tetrabutyldistannoxanes catalyze acetilization of carbonyl compounds under mild conditions. Thorough investigations of factors influencing this reaction are given. A variety of synthetically useful carbonyl compounds are efficiently converted to acetals. In particular, acetilization of cyclic α,β-unsaturated ketones is readily achieved which have met with only limited success so far.
