Boronic acids are often used in metal-catalyzed cross-coupling for C-C, C-N bond formation, and C-H functionalization. The widely utilized Suzuki-Miyaura coupling allows for the coupling of boronic acids with carbon halides and surrogates. Other known chemistry may includes 1,4-addition to activated alkenes, 1,2-addition to carbonyls and imines, addition to anhydrides, 1,4-addition to a,ß-unsaturated ketones(4), and 1,4-addition to esters and amides.


Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
