| Abstract: | A combined Lewis acid catalyst of InCl(3) and Me(3)SiBr promoted the direct use of enol acetates in the coupling with low-reactive silyl ethers, in which functional groups including ketones and aldehydes survived. Sterically hindered silyl ethers such as ROSiEt(3), ROSiPh(3), ROSit-BuMe(2), and ROSii-Pr(3) were also applicable. |
