A simple and efficient synthesis of 1(2H)-phthalazinone derivatives was achieved via reaction of phthalaldehydic acid and various phenyl hydrazines in acetonitrile using HClO4-SiO2 as a catalyst in very good yields. J. Heterocyclic Chem., 46, 351 (2009).

The heterocyclic mesomeric betaines 6a–c reacted with dimethyl acetylenedicarboxylate and ethyl propiolate giving the 1,3-dipolar cycloaddition products 7a–c and 8a–c, respectively. With esters of maleic, fumaric, acrylic and methacrylic acids, mesomeric betaines 6a and 6b gave substituted tetralone derivatives.
