Unprecedented aryl-to-aryl 1,5-rhodium migration is involved in decyanative silylation of aryl cyanides bearing a tethered arene. The 1,5-migration proceeds through remote C-H bond activation. 1,5-Migration also occurs in other rhodium-catalyzed reactions, including borylation and oxidative Mizoroki-Heck reactions.
芳基腈上带有桥连芳烃的去氰基硅化反应中涉及到前所未有的芳基至芳基 1,5-铑迁移。1,5-迁移通过远程 C-H 键活化进行。1,5-迁移也发生在其他铑催化反应中,包括硼化和氧化 Mizoroki-Heck 反应。
