ChemInform Abstract: Action of Iodine Monochloride, Iodine Monobromide and Iodine on Aromatic Acetals.

Abstract

ChemInform Abstract Reaction of ICl with aromatic acetals in the absence of light produces poor yields of the corresponding esters together with high yields of the corresponding aldehydes. Light-induced reactions, however, give high yields of the esters and poor yields of the aldehydes. When the same reactions are carried out with IBr, the formation of esters and aldehydes is also observed but the yields of esters cannot be improved in the presence of light. Reaction of iodine with aromatic acetals affords only the corresponding aldehydes.
