Abstract

Abstract : The first C5-protonated 1, 3-imidazole-based mesoionic carbene (iMIC Bp ) has been isolated and characterized by single-crystal X-ray diffraction. Abstract : The first C5-protonated 1, 3-imidazol-based mesoionic carbene iMIC Bp (2 ) (iMIC Bp = :C{CH(NDipp)2 C(Bp)}; Dipp = 2, 6-iPr2 C6 H3 ; Bp = 4-PhC6 H4 ) has been reported as a crystalline solid. Spectroscopic, X-ray diffraction, and computational studies clearly support the carbenic nature of 2, which has been further corroborated by its reactions with Ni(CO)4, (Me2 S)AuCl, white phosphorus, and CO2 .
