We developed a simple, efficient, and selective method for preparing organic Carbamates and carbonates using a catalytic amount of indium. A wide range of carbamates and carbonates were synthesized in high yields. The method is also applicable to the selective protection of amino groups under mild conditions. (C) 2009 Elsevier Ltd.
