Hydrolysis and hydrazinolysis of isatin-based ald-and ketazines

, (2015)
The hydrolysis of isatin aldazine 4a-d afforded the unexpected 3,3'-(hydrazine-1,2-diylidene)bis(indolin-2-one) (5) and 1,2-di(arylidene)hydrazines 6a-d through dual hydrolysis of 4a-d. A mechanism to explain the formation of 5 and 6a-d was proposed. In addition, the hydrazinolysis of 4a-d yielded 3-hydrazonoindolin-2-one (2) and 1,2-di(arylidene)hydrazines 6a-d instead of hydrazones 17a-d, while hydrazinolysis of isatin ketazine 5 gave the expected 3-hydrazonoindolin-2-one (2). These results indicated the ability of the title compounds for unusual hydrolysis and hydrazinolysis reactions.
