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.
