A stereoselective hydrogenation of 1,3-diynes with an air-stable copper(I)/N-heterocyclic carbene complex, [IPrCuOH], has been developed. The corresponding products, 1,3-dienes, are obtained in a stereoselective manner depending on their substitution pattern: Diaryl-diynes yield E,E-1,3-dienes, whereas dialkyl-diynes are converted to the corresponding Z,Z-1,3-dienes. Hydrogenation and deuteration experiments
已经开发了用空气稳定的铜(I)/ N-杂环卡宾络合物[IPrCuOH]进行1,3-二炔的立体选择性氢化。取决于其取代方式,以立体选择的方式获得相应的产物1,3-二烯:二芳基-二炔产生E,E -1,3-二烯,而二烷基-二炔转化为相应的Z,Z -1 ,3-二烯。烯炔的氢化和氘化实验表明,这些是二炔氢化中有效的反应中间体。
