## Abstract The reaction of 3‐chloro‐6‐phenyl‐1,2,4‐triazine **1a** with carbon nucleophiles **2aο£Ώd** bearing a cyano substituent at a carbanionic center has been studied. In all reactions the formation of the corresponding 3‐aminopyridazines **3aο£Ώd** takes place via ANRORC mechanism involving addi
