Abstract

Silicon-bridged bis(benzene)chromium complexes (sila[1]chromarenophanes) undergo facile transition metal-catalyzed ROP at ambient temperature in the presence of Karstedt's catalyst to yield polychromarenylsilanes, the first homopolymers with main chains of Cr(arene)(2) and organosilane units.
