Molecular Sieves as a New, Highly Efficient, Inexpensive and Reusable Catalyst for N-Ter-Butoxycarbonylation of Amines

Venugopal V Durvasula and Binny Khanna

Molecular sieves was found to be a new catalyst for chemoselective N-tert-butoxycarbonylation of amines at room temperature and under solvent-free conditions for range of amines, which includes acyclic, aromatic and sterically hindered amines. Environmental benignity, cost effectiveness, and high yields are the important attributes of the present procedure.
