Green and efficient protocol for N-alkylation of benzotriazole using basic ionic liquid [Bmim]OH as catalyst under solvent-free conditions

摘要

N-Alkylation of benzotriazole bearing an acidic hydrogen atom attached to nitrogen with alkyl halides is accomplished in basic ionic liquid [Bmim]OH (1-butyl-3-methylimidazolium hydroxide) under solvent-free conditions. The procedure is convenient and efficient and generally affords the N-alkylated product.
