Reactions of the Lewis acids BH 3 and BEt 3 with trimethylimidazole (1) lead to the borane adducts 2a and 2b. Deprotonation of 2a with n-butyllithium results in the formation of the novel N-borane-substituted imidazol-2ylidene anion 3a -whereas deprotonated 2b rearranges unexpectedly to the anionic
