Rapid and Mild Synthesis of an NHC-Coordinated Bis(trimethylsilyl)silylene via Elimination of Halotrimethylsilane

Base-coordinated silylenes are often used as electron-donating ligands for metal complexes and low-coordinate species of main group elements. However, the synthesis routes to base-coordinated silylenes remain limited. Herein, we report a rapid and mild reaction providing NHC-coordinated bis(trimethylsilyl)silylene 2, which includes the coordination of 1,3,4,5-tetramethylimidazol-2-ylidene (IMe4) to (Me3Si)3SiX (1, X= Cl, Br, and I) and the...
