文摘A novel synthesis of several isocyanates by direct electrocatalytical carbonylation of corresponding amines can proceed through an electrochemically regenerable palladium(Ⅱ) catalyst in combination with copper acetate as cocatalyst with an excellent conversion and selectivity under mild conditions. The results show that Pd(PPh 3) 2Cl 2 was the best catalyst. For aromatic amines, the main products were the corresponding isocyanates. And for aliphatic amines, various products were detected.
