Synthesis of Carbamates Using Yttria-Zirconia Based Lewis Acid Catalyst

Abstract

A variety of amines react with chloroformates in the presence of catalytic amount of yttria-zirconia based catalyst to afford the corresponding carbamates in excellent yields.

Keywords:

• Yttria-zirconia based Lewis acid
• Heterogeneous catalysis
• Carbamate
• Chemoselectivity
