WebTreatment of 1-hexene with BMB, for example, gives after oxidation, 99% 1-hexanol and 1% 2-hexanol. Moreover, BMB is found to react only very slowly with di- or trisubstituted olefins, and can therefore be conveniently used as a selective hydroborating agent in the case of variously substituted polyenes. Web2-methyl-1-hexanol was prepared by reacting an alkene with either hydroboration-oxidation or oxymercuration-reduction.
