Organo-silanes, germanes, and stannanes are considered to be conducive to the development of cross-coupling reactions because they are stable, nontoxic, and easy to handle. Using feedstock toluenes, one-pot direct benzylic C–H silylations, germylations, and stannylations are developed. Simply combining toluenes, LiN(SiMe3)2/CsCl, and R3MCl (M = Si, Ge, Sn) generates a diverse array of bench-stable
有机硅烷、锗烷和锡烷被认为有利于交叉偶联反应的发展,因为它们稳定、无毒且易于处理。使用原料甲苯,开发了一锅直接苄基 C-H 甲硅烷基化、胚芽化和单烷基化。简单地将甲苯、LiN(SiMe 3 ) 2 /CsCl 和 R 3 MCl (M = Si、Ge、Sn) 组合起来,就可以生成各种台式稳定的苄基硅烷、锗烷和锡烷(38 个例子,53-90% 的产率)。这里开发的合成很容易大规模访问。
