Abstract:

Bis(9H-9-borabicyclo[3.3.1]nonane) reacts with pyrazole and its 4-bromo, 3-Me, 3-Ph, 3,5-di-Me, 3-methyl-5-Ph, 3,5-di-Ph, 3,5-di-tert-Bu, 3,5-diadamantyl, 3,5-di-tert-butyl-4-Me, and 3,5-di-tert-butyl-4-Et derivs. to give the 9-pyrazolyl-9-borabicyclo[3.3.1]nonanes with the dimeric e.g. I and monomeric structures. The crystal structures of 4 of the prepd. compds. were detd.
