One-step conversions of 1,3-disubstituted benzenes to aryl boronates and 2,6-disubstituted pyridines to heteroaryl boronates are described. Microwave heating was used for all reactions. [(COD)Ir(μ-OMe)]2 and 4,4′-di-tert-butyl-2,2′-bipyridine were used as catalysts, in methyl tert-butyl ether. Acceleration of the rate of reaction was remarkable compared with that of same reaction under conventional heating conditions.
一步法将1,3-二取代苯转化为芳基硼酸盐,以及将2,6-二取代吡啶转化为杂芳基硼酸盐的反应被描述。所有反应均采用微波加热。使用[(COD)Ir(μ-OMe)]2和4,4′-二叔丁基-2,2′-联吡啶作为催化剂,溶剂为甲基叔丁基醚。与传统加热条件下的相同反应相比,反应速率的加速效果显著。
