Treatment of (E)-alk-1-enyldicyclohexylboranes 1 with diisobutylaluminium hydride (DIBAL-H) in the presence of hex-1-ene at room temperature results in transfer of the alk-1-enyl group from boron to aluminium to give (E)-alk-1-enyldiisobutylalanes 2 with retention of configuration at the double bond.

The thermal isomerizations of 3-hexyldicycloalkylboranes were compared under identical conditions. The rate of thermal isomerization of 3-hexyldicyclooctylborane (7) is approximately 7 times greater than that of 3-hexykJicycloheptylborane (6), about 33 times more than that of 3-hexyldicyclohexylborane (3), and nearly 100 times greater than the rate of 3-hexyldicyclopentylborane (5), a discovery of great importance in understanding the high dependence of the rate and equilibrium of isomerization on the size of the cycloalkyl substituents present on the boron atom.
