Suzuki cross-coupling reactions of an unprecedented array of unactivated primary and secondary alkyl halides (including challenging alkyl chlorides) can be accomplished through the use of nickel/amino alcohol-based catalysts. Both the nickel precatalyst and the amino alcohols (prolinol or trans-2-aminocyclohexanol) are commercially available and air-stable. In view of the remarkable diversity of amino alcohols that are readily accessible, this discovery may open the door to the rapid development of versatile catalysts for a wide range of cross-coupling processes.
通过使用镍/氨基醇基催化剂,可以实现前所未有的一系列未活化伯卤代烃和仲卤代烃(包括具有挑战性的氯代烃)的铃木交叉偶联反应。镍预催化剂和氨基醇(脯氨醇或反式-2-氨基环己醇)均可商购且对空气稳定。鉴于易于获得的氨基醇具有显著的多样性,这一发现可能为广泛的交叉偶联过程快速开发通用催化剂打开大门。
