Volume 2, Issue 1, pp. 1-81, Serial No. 2 , January 2014, , Pages 72-81

Abstract
  1,1-Diacetates(acylals) were prepared by direct condensation of various aldehydes with acetic anhydride using dipyridine cobalt chloride (CoPy2Cl2) as an efficient and green catalyst under solvent-free conditions at room temperature. The important features of this catalyst method are that the catalyst ...  Read More
