hydroboration of 1,4-cyclooctadiene with 1a–c leads to mixtures of products containing both the 9-borabicyclo[3.3.1]nonane (6a–c) and the 9-borabicyclo[4.2.1]nonane derivative (7a–c). In the case of the reaction of 1d with 1,4-cyclooctadiene, the 9-(N-carbazolyl)-9borabicyclo[4.2.1]nonane 7d is formed selectively. The reaction of the corresponding tetraalkyldiboranes(6) with the azoles gives the boracyclopentane
