Abstract

Various substituted 1, 1-diacetates are smoothly transformed to the corresponding aldehydes by using hydrated ferric sulfate as heterogeneous catalyst at reflux in dichloroethane. The advantages of this methodology are: high yields, good chemoselectivity, inexpensive and environmentally benign catalyst as well as short reaction time and operational simplicity.
