Cu2O was found to be an efficient and economical metal catalyst in the Ullmann cross-coupling reaction of vinyl bromides with imidazole or benzimidazole. The system Cu2O/ethyl 2-oxocyclohexanecarboxylate showed high catalytic activity in MeCN at 80–90 °C. The reaction gave the corresponding coupling products in good to excellent yields.
在乙烯基溴与咪唑或苯并咪唑的Ullmann交叉偶联反应中,发现Cu 2 O是一种有效且经济的金属催化剂。Cu 2 O / 2-氧代环己烷甲酸乙酯体系在80–90°C的MeCN中显示出高催化活性。该反应以良好至优异的产率得到相应的偶联产物。
