A highly chemoselective platinum-catalyzed mono-lateral diboration of dialkynylsilanes for the construction of silicon-tethered alkynyl diborylalkenes is described, in which tris(4-methoxyphenyl)phosphine was found to be an effective ligand for the cis-addition of diboron agents to the silicon-tethered alkynes, and the chiral ligand (AFSi-Phos)-mediated diboration of dialkynylsilanes resulted in the desymmetric construction of silicon-stereogenic centers with promising enantioselectivity.
本文描述了一种用于构建硅连接的炔基二硼基烯烃的高度化学选择性铂催化二炔基硅烷单边双硼化反应，其中发现三（4-甲氧基苯基）膦是二硼试剂顺式加成到硅连接的炔烃上的有效配体，并且手性配体（AFSi-Phos）介导的二炔基硅烷双硼化反应导致了具有良好对映选择性的硅立体中心的去对称构建。
