Product Description

Trimethyl borate reacts with a Grignard reagent or organolithium compounds to yield dimethyl boronates, which upon subsequent aqueous acid treatment afford corresponding boronic acids. The resultant boronic acids or esters are useful intermediates in various cross-coupling reactions such as Suzuki coupling and Chan-Lam coupling.It is also used in the preparation of sodium borohydride.
