A Stable Silene Substituted by Strong π-Donors at the Silicon Center

Abstract : A stable and isolable silene with two π-donating groups on the silicon center has been synthesized. This silicon-substituted silene shows totally different π-substituent effects compared to those of related carbon-substituted silenes, and it presents intrinsic silene properties with an enhanced electron-donating character, making it an excellent ligand for transition metals.
