Use of isomeric, aromatic dialdehydes in the synthesis of photoactive, positional isomers of higher analogs of o-bromo(hetero)acenaldehydes

Abstract

A series of photoresistant, positional isomers of o-bromo(hetero)acenaldehydes containing RO-Ar and bifunctional ortho-CHO/Br structural motifs, is available in the peculiar Friedel–Crafts modification, using isomeric aromatic o,o-dibromodialdehydes.
