Abstract

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