【摘要】通过筛选一系列有机溶剂,发现在吡啶中,以碳酸钾作碱,价廉易得的NiCl2.6H2O能催化芳基硼酸发生自身偶联反应生成对称的联芳烃,该反应收率较高,并可暴露在空气中进行.更多还原

【Abstract】 By screening different organic solvents, it was found that NiCl₂·6H₂O can catalyze the homocoupling of arylboronic acids using K₂CO₃ as the base in pyridine to produce symmetrical biaryls in good yield. This reaction can be carried out with exposure to air.更多还原
