CAS 94242-85-0

Methyl boronic acid pinacol ester

Description:

Methyl boronic acid pinacol ester, with the CAS number 94242-85-0, is an organoboron compound characterized by the presence of a boron atom bonded to a methyl group and a pinacol ester moiety. This compound typically appears as a colorless to pale yellow liquid or solid, depending on its purity and form. It is known for its utility in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura coupling, where it acts as a boron source for the formation of carbon-carbon bonds. The presence of the pinacol ester enhances its stability and solubility in organic solvents, making it a valuable reagent in various chemical transformations. Methyl boronic acid pinacol ester is generally sensitive to moisture and air, necessitating careful handling and storage under inert conditions. Its reactivity is attributed to the boron atom, which can participate in nucleophilic attacks and coordinate with other electrophiles, making it a versatile intermediate in the synthesis of pharmaceuticals and agrochemicals.
