A comparison between the facial selectivity observed in the hydroboration of some androst-5-enes and B-norandrost-5-enes does not parallel the differences between the calculated force field energies of α- and β-cyclobutane models suggesting that in this case the facial selectivity is not determined by the four centre transition state but by the ease of formation of the initial ?-complexes between the alkene and the borane.
