Abstract
Symmetric ureas were synthesized with high efficiency and selectivity by ox idative carbonylation of aromatic and aliphatic amines in the presence of r esin immobilized gold, e.g. 1475 of TOF and 99% of selectivity were achieve d when using aniline as the substrate. No other organic solvent was used in the reactions and highly pure products could be obtained due to the high s electivity and the easy separation of the catalyst from the reaction system .
