site-selective, double, or alkynylative cross-coupling, therefore providing divergent and straightforward entries to numerous building blocks such as bromoenamides, ynamides, ketene N,N-acetals, bromoenol ethers, ynol ethers, ketene O,O-acetals, or vinylphosphonates and further expanding the copper catalysis toolbox with useful and versatile processes.
据报道,有效的和通用的程序是将1,1-二溴代烯烃与N-,O-和P-亲核试剂进行交叉偶联。反应条件的微调允许位点选择性,双重或炔基交叉偶联,因此为许多结构单元(如溴酰胺,乙酰胺,乙烯酮N,N-乙缩醛,溴烯醇醚,炔醇醚)提供了分散而直接的入口,乙烯酮O,O-乙缩醛或乙烯基膦酸酯,并通过有用的通用方法进一步扩展了铜催化工具箱。
