摘要
Abstract We have reported an efficient and eco-friendly protocol for the protection of various structurally and electronically divergent aryl and aliphatic amines using (Boc)2O in the presence of PEG-400 at room temperature. The reaction gave excellent yields with low as well as high molecular weight PEGs.
