Isomerization of 1-(9-borabicyclo[3.3.1]nonan-9-yl)oct-4-yne, readily prepared by hydroboration of oct-1-en-4-yne with 9-borabicyclo[3.3.1]nonane and 2·5–3·0 equiv. of potassium 3-aminopropylamide, yields quantitatively 1-(9-borabicyclo[3.3.1]nonan-9-yl)oct-7-yne, which undergoes typical organoborane, reactions such as oxidation and alkyltransfer to α-bromoketones.

Ab initio calculations at the HF/3-21G level predict that both sup 1}Csub 2} and sup 3}Csub 2} will add to ethylene without barrier. At the MP2/6-31G*//3-21G level, the triplet adduct is calculated to be more stable than sup 3}Csub 2} and ethylene by 46.0 kcal/mol. The reactions of sup 1}Csub 2} and sup 3}Csub 2} with methane and hydrogen have also been investigated theoretically.
