Bellesia, Franco,Boni, Monica,Ghelfi, Franco,Grandi, Romano,Pagnoni, Ugo M.,Pinetti, Adriano

, p. 4579 - 4586 (2007/10/02)

α-Chloroacetals are obtained in almost quantitative yields, by treating acetals with MnO2-trimethylchlorosilane in CH3OH:CH3CN (1:1).The halogenation is explained by a ligand-transfer process on an enolether intermediate, mediated by a Mn(IV)-chloride species.Key Words: Acetals, Aldehydes, Chlorination, Maganese(IV)oxide, Trimethylchlorosilane, Ligand-transfer
