Neopentylboronic acid（Cat No.:L038061）is an organoboron compound featuring a boronic acid group attached to a neopentyl moiety, a highly branched alkyl group with the formula (CH₃)₃CCH₂–. Its sterically hindered structure provides enhanced stability and selectivity in cross-coupling reactions, particularly Suzuki-Miyaura couplings, where it serves as a valuable building block for forming carbon–carbon bonds. The boronic acid group offers versatile reactivity with aryl or vinyl halides, while the bulky neopentyl group helps reduce side reactions. Neopentylboronic acid is widely used in pharmaceutical and materials chemistry for synthesizing complex, functionalized organic molecules.
