## Abstract An efficient synthesis of 5‐heteroaryl‐ and 5,7‐bis(heteroaryl)azulene derivatives was established for first time. The reaction proceeded through electrophilic substitution of 1,3‐di‐__tert__‐butylazulene (**1**) with the triflates of N‐containing heterocycles, in the presence of excess
