We thought to test this proposal by studying the effect of varying the benzenesulfonyl group on the rate of decomposition. Preliminary studies were carried out on benzenesulfonylbenzhydrazide (I). Surprisingly, it was discovered that when homogeneous solutions of the sodium or potassium salt of I in ethylene glycol were heated to 160-165'no appreciable evolution of nitrogen occurred. In the conventional procedure for carrying out ...
