Ready preparation of trialkoxyboranes and dialkoxyboranes by LiBEt3H-promoted reaction of BH3 in tetrahydrofuran with alcohols
A catalytic amount of LiBEt3H (1%) promoted markedly the reactions of BH3 in tetrahydrofuran (THF) with stoichiometric amounts of alcohols (1:2 and 1:3) to provide corresponding trialkoxyboranes and dialkoxyboranes quantitatively under mild reaction conditions.
