摘要：
A new Ru3(CO)12-catalyzed directed alkenylation of2-carboxaldimine-heterocyclopentadienes has been accomplished.This process allows coupling of furan, pyrrole, indole, andthiophene 2-carboxaldimines with electron-poor alkenes such asacrylates, vinylsulfones, and styrenes. This regio- and chemo-selective oxidative C-H coupling does not require the presence ofan additional sacrificial oxidant. Density functional theory calculations allowed us to propose a mechanism and unveiled the nature ofthe H2acceptor.
