Bis(9H-9-borabicyclo[3.3.1]nonane) (9H-9-BBN)2 reacts with pyrazole (Pz) and its 4-bromo, 3-methyl, 3-phenyl, 3,5-dimethyl, 3-methyl-5-phenyl, 3,5-diphenyl, 3,5-di-ert-butyl, 3,5-diadamantyl, 3,5-di-tert-butyl-4-methyl, and 3,5-di-tert-butyl-4-ethyl derivatives [brPz, mPz, pPz, m2Pz, mpPz, p2Pz, (tb)2Pz, (ad)2Pz, (tb)2mPz, and (tb)2mPz, and (tb)2ePz, respectively] to give the 9-pyrazolyl-9-borabicyclo[3.3.1]nonanes with the dimeric structure (1)2-(3)2 (X-ray, NMR, and MS analysis), and 4-11 with monomeric structures (X-ray, NMR, MS).
