Let's coordinate: Copper(I)‐catalyzed cross‐coupling of alkenyl‐ and arylsilanes with primary alkyl iodides as well as allylic and benzylic halides as C(sp3)X electrophilic coupling partners has been realized by intramolecular activation through alkoxide coordination. This alkylation tolerates a range of functional groups including a free hydroxy group. IPr=1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylidene
让我们坐标:铜(I)催化的链烯基和芳基硅烷与伯烷基碘以及烯丙基和苄基卤化物如C(SP交叉耦合3)通过醇盐的分子内配位活化已经实现X电偶联伴侣。这种烷基化容许包括游离羟基在内的一系列官能团。IPr = 1,3-双(2,6-二异丙基苯基)咪唑-2-亚烷基。
