Attempts toward a Silyl-Stabilized Dicoordinate Borylene: Insertion of Carbon Dioxide into the B-Si Bond.

ABSTRACT: One-electron reduction of the carbene-stabilized borane (Me₂-cAAC)B(Cl)₂Si(SiMe₃)₃, 1, with potassium naphthalenide gave the radical (Me₂-cAAC)B(Cl)Si(SiMe₃)₃, 2. A subsequent one-electron reduction of 2 yielded the dicoordinate borylene (Me₂-cAAC)BSi(SiMe₃)₃, 3, which rapidly underwent intramolecular C-H activation to give cyclo-(Me₂-cAAC)B(H)Si(SiMe₃)₃, 4, irrespective of the employed reaction conditions. Compound 3 could be stabilized as the carbonyl complex (Me₂-cAAC)B(CO)Si(SiMe₃)₃, 5, that gave 4 upon irradiation with a UV light under a CO₂ atmo
