Abstract

The reactions of 2-tosyloxytropones or 2-chlorotropones with hydrazine, methylhydrazine, and phenylhydrazine gave 2-hydrazinotropones, 2-(α-methylhydrazino)-tropones, and 2-(β- phenylhydrazino) tropones, respectively. All the reactions are normal substitution at C-2 position of the tropone ring. No ciné reaction was observed. The reactivity of hydrazines decreases in the order: NH 2 NH 2> CH 3 NHNH 2>> PhNHNH 2.
