## Abstract The reaction of 3โ€chloroโ€6โ€phenylโ€1,2,4โ€triazine **1a** with carbon nucleophiles **2a๏ฃฟd** bearing a cyano substituent at a carbanionic center has been studied. In all reactions the formation of the corresponding 3โ€aminopyridazines **3a๏ฃฟd** takes place via ANRORC mechanism involving addi
