Notizen:
Imidazole Derivatives, VI[1]. - Stable Carbene BoranesStable imidazol-2-ylidene - borane adducts 8 and 9 are obtained from 1,3,4,5-tetraalkylimidazol-2-ylidenes 7 and Me2S BH3 or Et2O BF3. An X-ray structure analysis of 8b has been performed. An ab initio calculation [MP2(fu)/6-31G**] reveals a low energy difference between two rotamers. The bond orders of the cyclic bonds imply only a minor interaction between the N - C - N and the C - C fragment.
