Efficient and recyclable heterogeneous zinc alkyl carboxylate catalyst for the synthesis of N-phenyl carbamate from aniline and dimethylcarbonate

Abstract

Zinc alkyl carboxylate molecules were chemically bonded on a silica surface through an elaborately designed precursor agent and special grafting method. The heterogeneous salt catalyst possessing a cyclic single active site was highly active and recyclable in the reaction between dimethylcarbonate and aniline to produce methyl N-phenyl carbamate.
