Abstract
Reaction of 4‐chloro‐3,6‐diphenylpyridazine with potassium amide in liquid ammonia gives 4‐amino‐3,6‐diphenylpyridazine and imino‐4,4′‐bis(3,6‐diphenylpyridazine). Starting with 4‐chloro‐3,6‐diphenylpyridazine‐[5‐13C], it was proved by quantitative 13CNMR measurements that both products are formed via the intermediacy of 4,5‐didehydro‐3,6‐diphenylpyridazine.Keywords
