Abstract

Carbonyls and acetals are converted to lS-dithianes and-dithiolanes upon treatment with 2- stannal, &dithianes and-dithiolanes under catalysis by organotin triflates. In these competition reactions, various types of carbonyls and acetals are differentiated. Aldehydes react preferentially over ketones, but the preference is completely reversed in the competition reactions between the corresponding acetals and ketals. The reactivity of ...
