Abstract

The first C5-protonated 1,3-imidazol-based mesoionic carbene iMIC^Bp (2) (iMIC^Bp = :C{CH(NDipp)₂C(Bp)}; Dipp = 2,6-iPr₂C₆H₃; Bp = 4-PhC₆H₄) 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, (Me₂S)AuCl, white phosphorus, and CO₂.
