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.

Borates, compositions comprising chiral (cyclic and acyclic) and achiral (cyclic and acyclic) borates; chiral (cyclic and acyclic) and achiral (cyclic and acyclic) biborates; and methods for their synthesis. Additionally, a significantly improved synthetic protocol for the synthesis of wide range of boronates starting from borates or biborates and Grignard or organolithium reagents that can be used for kilo lab and commercial scale production.
