Abstract

We have developed an efficient protocol for synthesis of 2-(substituted phenyl) phthalazin-1(2H)-ones from Phthalaldehydic acid, substituted phenyl hydrazine using Nano TiO2 as a catalyst. Simplicity, short reaction time, easy work up, cheap catalyst, good yield are the major advantages of the proposed method.
