Abstract：
Multisubstituted olefins are fundamental motifs in organic compounds. In this account, we describe the synthesis of organic molecules bearing an olefinic moiety by the transition-metal-catalyzed regio- and stereoselective addition of a variety of interelement compounds to alkynes. Regio- and stereoselective silaboration, diborylation, and chlorothiolation have been achieved by using the transition-metal catalysts. The subsequent cross-coupling reactions of the boron-containing alkenes to install various aryl groups afforded the corresponding tri- and tetraarylated olefins. This account describes our research on the highly regio- and stereoselective synthesis of multifunctionalized olefins such as tetraarylethenes with four different aryl groups.
摘要：
多取代的烯烃是有机化合物中的基本基序。在这个账户中，我们描述了通过过渡金属催化的各种相互作用化合物与炔烃的区域和立体选择性加成来合成带有烯属部分的有机分子。区域和立体选择性硅化，二硼化，通过使用过渡金属催化剂已经实现了氯硫醇化。随后的含硼烯烃的交叉偶联反应以安装各种芳基,得到相应的三-和四-芳基化的烯烃。该帐户描述了我们对多官能化烯烃（例如具有四个不同芳基的四芳基乙烯）的高度区域和立体选择性合成的研究。
