Abstract
The stable carbene 1,2,3,5-tetramethylimidazol-2-ylidene forms an adduct with 3,5-dimethylborabenzene. This adduct 8 can readily be made from the carbene and 1-chloro-3,5-dimethyl-2-(trimethylsilyl)-1,2-dihydroborinine (6) as colorless crystals. The structure of 8 is closer to that of the anion in NMe3Ph(C5H5BMe) (9) than to the structures of known betainic adducts. There is no noticeable conjugation between the borabenzene and the imidazol-2-ylidene moieties.
