Polymer-immobilized gold catalysts for the efficient and clean syntheses of carbamates and symmetric ureas by oxidative carbonylation of aniline and its derivatives
A series of highly efficient polymer-immobilized gold catalysts were prepared for the oxidative carbonylation of aniline and its derivatives to obtain carbamates and symmetric ureas in a clean, simple, solvent-free, and obtainable product-ready way. TEM showed that the average gold particle size of fresh catalyst was less than 10 mm.
