TRANSITION-METAL-CATALYZED BORYLATION OF ORGANIC HALIDES WITH HYDROBORANES

Metal-catalyzed cross-coupling reaction of B-H compounds provides a direct method for conversion of C-X bonds to C-B bonds. Dialkoxyboranes are excellent boron sources in the borylation of aryl, 1-alkenyl, allyl or benzyl halides or pseudohalides. These reactions tolerate large number of functional groups and proceeds with excellent yields, thereby allowing the simple, convenient, and elegant preparation of functionalized C-B compounds.
