Abstract Reaction of 1, 3-bis (dimethylamino) trimethinium perchlorate (1) with 3-substituted prop-2-ynals (4) in acetic anhydride at the presence of ZnBr 2 gives upon hydrolysis 1- substituted 2, 4, 6-triformylbenzenes (6) in low to moderate yield. This reaction is restricted to prop-2-ynals bearing electron rich aromatic substituents at the 3-position.
