Abstract
N-Acylbenzotriazoles are useful acylating agents, especially where the corresponding acid chlorides are unstable, difficult to prepare, or unknown. Reactions with N-acylbenzotriazoles offer efficient transformations under mild conditions, and provide an alternative convenient procedure for N-, C-, S-, and O-acylation. In this account, our work mainly carried out from 2000 to early 2005 is discussed.
