Hm. Meshram et al., Microwave thermolysis VI: A rapid and general method for dethioacetalization using "Clayan" in dry media, SYN COMMUN, 29(7), 1999, pp. 1113-1119
A variety of thioacetals, dithiolanes and dithianes are deprotected into th
eir carbonyl compounds using clay supported ammonium nitrate "Clayan" under
microwave irradiation. The present method avoids the use of toxic oxidants
and excess of solvent.
