Thioacetals are cleaved into aldehydes and ketones, under very mild conditions, by K-10 clay-supported ferric or cupric nitrate. WIDESPREAD use is made of thioacetals in organic synthesis, mostly for protection or umpolung of the reactivity of a carbonyl groupI. Regeneration of the carbonyl function
