4-Aryl-2-phenyl-1,2-dihydrophthalazine-1-thiones react with nitrile imides according to the [3 + 2]-cycloaddition pattern to give phthalazinespirothiadiazoles. The reaction occurs regioselectively at the exocyclic C=S bond.

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 thionederivatives 3a–c or the chloro derivative 4 respectively. Further reactions of phthalazines 3 and 4 with hydrazine derivatives afforded their hydrazinyl derivatives 5a–d. Compounds 5a and 5d were used
