regioselective cyanation of heteroaromatic N‐oxides with trimethylsilyl cyanide has been developed to obtain 2‐substituted N‐heteroaromatic nitrile without the requirement of any external activator‐, metal‐, base‐, and solvent. The present protocol is a straightforward, one‐pot heteroaromatic C−H cyanation process, and proceeds smoothly in conventional heating but also under microwave irradiation with shorter
