The presence of triethylborane dramatically accelerated the reduction of epoxides with lithium borohydride. Thus the all three epoxides tested, namely, 1,2-butylene oxide, cyclohexene oxide and styrene oxide were reduced rapidly in 1 h at room temperature in the presence of 25 mole % of triethylborane whereas more than 24 h was required for these reductions with lithium borohydride itself.
