Simple and Efficient Oxathioacetalization of Aldehydes Using Anhydrous Cobalt (II) Bromide under Solvent-Free Condition

A simple and efficient method has been developed for the oxathioacetalization of aldehydes using anhydrous cobalt (II) bromide. The remarkable selectivity under mild and neutral conditions, excellent yields, solvent-free condition, short reaction time, easy availability and inexpensive catalyst are some important features of this method
