coupling of two strong electrophilic bonds has been less developed. We report here silylationreactions that proceed by coupling of strong Si–Cl/C–O bonds in a process that is promoted by chromium catalysis via α-agostic SiH → Cr interactions, allowing the formation of Si–C bonds under ambient conditions. The reactions occur by coupling of inexpensive hydrochlorosilanes with unactivated aryl carboxylic

C−Si bond-forming reaction between R−X and Cl−Si(H)R2 was achieved using reductive nickel catalysis. This method offers access to structurally diverse aryl- and alkenylhydrosilanes from phenol and ketonederivatives. The reaction can be conducted on gram scale and allows for incorporating a hydrosilane moiety into biologically active molecules.
