## Abstract The synthesis of 2‐substitutedimidazo[1,2‐__b__]pyridazines and their reactivity towards electrophilic substitutions are reported. The nitration was shown to be very dependent on the nature of the 2 substituent. Nitrosation using sodium nitrite in acetic acid media as a general method f
