lyzed activation of silyl C(sp3)–H bond was realized and synthetically applied. A variety of organic skeletons substituted with SiMe3 groups could undergo the Pd-catalyzed intramolecular coupling reaction, resulting in an unprecedented synthetic method for yielding six-membered silacycles. It was found that the adjacent Si atom played an essential role for the activation of the C(sp3)–H bond of the
甲硅烷基C(sp 3)–H键的第一个过渡金属催化活化作用得以实现并得到了合成。各种被SiMe 3基团取代的有机骨架都可以进行Pd催化的分子内偶联反应,从而产生了一种空前的合成方法,可生产六元silacycles。发现相邻的Si原子对于激活SiMe 3基团的C(sp 3)-H键起着至关重要的作用。在相同的反应条件下,没有发生CMe 3基团的C(sp 3)–H键的活化反应。
