  Vinylborane and vinylchalcogenide mediated synthesis of tri- and tetrasubstituted olefins from 1-alkynes

  摘要：

  The title olefins have been prepared with high regio- and stereocontrol from I-alkynes through vinyl boranes / vinyl chalcogenides; the reaction sequences involved protonolysis or transmetallation - alkylation of the boranes followed by an Ni(0) catalyzed coupling reaction.

  The reaction of 1-alkynyltrialkyl borates with sulfenyl, selenenyl and tellurenyl halides produces β-chalcogeno alkenylboranes in good yields, with a cis relationship between the boron and the chalcogen moities. Protodeborylation of these compounds by acetic acid, or by a transmetalation–protonolysis sequence, leads to vinyl chalcogenides, which can be converted to alkenes by means of a nickel catalyzed

  1-炔基三烷基硼酸酯与亚硫基，亚硒基和碲基卤化物的反应以良好的产率产生β-硫属元素烯基硼烷，其中硼与硫属元素之间具有顺式关系。这些化合物通过乙酸或通过金属转移-质子分解序列进行原脱硼化反应，生成乙烯基硫属元素化物，可以通过镍与格利雅试剂的偶联将其转化为烯烃。由于最后两个步骤是在保留立体化学的情况下发生的，因此整个序列代表了高度区域和立体选择性的烯烃合成。
