Selective dehydrogenative C–H silylation is one of the most powerful tools to synthesize silacycles. Herein, we developed Ru-catalyzed sequential hydrosilylation/C–H silylation of allyl-indoles and dehydrogenative O–H/C–H silylation of pyrrole phenols. Both six-membered indole silacycles and pyrrole silyl ether cycles were successfully synthesized with good functional group tolerance. Furthermore,
选择性脱氢C-H硅烷化是合成硅环最有力的工具之一。在此,我们开发了Ru催化的烯丙基吲哚的顺序氢化硅烷化/C-H硅烷化和吡咯酚的脱氢O-H/C-H硅烷化。成功合成了六元吲哚硅环和吡咯硅醚环,具有良好的官能团耐受性。此外,RuHCl(CO)(PPh 3 ) 3催化剂在烯烃氢化硅烷化、脱氢O-H硅烷化和C-H硅烷化中表现出高反应相容性。
