Starting from 2-benzoylbenzoic acid (1) and prototype hydrazine itself or some of its simple congeners produce phthalazin-1(2H)-one derivatives 2a-d. Reactions of 2 with P2S5 or POCl3 gave their thione derivatives 3a-c or

Hydrazones (Ia-c) fail to undergo cyclisation under different conditions to yield phthalazines (IIa-c). o-Aroylbenzoic acids (IVa-c) on treatment with hydrazine hydrate give 4-aryl-1(2H)-phthalazinones (Va-c) which react with POCl3 to yield 4-aryl-1-chlor
