Evidence, based on 15 N‐labelling studies, has been obtained that the amino‐dechlorination of 3‐chloro‐1,2,4‐benzotriazine by potassium amide in liquid ammonia occurs according to an S N (AE) ipso process, while the amino‐dechlorination of 3‐chlorophenanthro[9,10‐ e ]‐1,2,4‐triazine reacts for more than 90% according to a process involving a ring opening reaction [S N (ANRORC) ipos substitution].
