  摘要：

  The reaction of Me3CCOOBEt2 with pyrazole led to the formation of the stable addition complex 1, which was found to be monomeric in solution. The reaction of 9-H-9-borabicyclo[3.3.1]nonane (9-H-9-BBN)(2) with pyrazole and pivalic acid yielded a similar complex Me2CCOO(9-BBN)-pzH 2. Crystallographic analysis of 2 revealed a dimeric structure due to the strong hydrogen bonding between azole hydrogen and carbonyl oxygen. The one boron-carbon bond of compound 1 cleaves readily with triethylborane at 20 degrees C with the evolution of ethane, giving a species Me2CCOO(BEt2)(2)pz 3 with a seven-membered heterocyclic ring as the main structural feature.
