Brønstedacidicionicliquid, [HMIM][BF4], has been used as a non‐volatile, eco‐friendly solvent, and catalytic medium for the one‐pot greensynthesis of azidesfrom corresponding alcohols. The [HMIM][BF4] showed high reactivity than [BMIM][BF4] and [BMIM][PF6], affording azides in up to 97% yield, which could be easily separated from the reaction mixture. The ease of recyclability of [HMIM][BF4] makes
