Abstract
The preparation and characterization of five new imidazabole derivativ es is reported: 1,5-dibenzyl-4,4,8,8-tetrahydroimidazabole (2), 4,4,8, 8-tetrafluoro-1,5-dimethylimidazabole (3), 4,4-difluoro-8,8-dihydro-1, 5-dimethylimidazabole (4), 4,4,8,8-tetrachloro-1,5-dimethylimidazabole (5), and 4,4,8,8-tetraethyl-1,5-dimethylimidazabole (6). The structur es of compounds 2-6 as dimeric carbene-borane adducts rather than dime ric N-borane adducts are discussed on the basis of NMR (2-6) and X-ray diffraction data (2, 3, 5 and 6).
