| Application: | Tetrahydroxydiboron (BBA) is an efficient borylating agent that can be used to borylate a wide variety of aryl and heteroaryl substrates with low Pd- and Ni-catalyst loads. Other reactions employing BBA as a reagent: • Palladium-catalyzed boronation of vinyl cyclopropane, vinyl aziridine, and allyl acetate substrates. • To facilitate catalytic transfer hydrogenations of simple alkenes and alkynes. • Selective reducing agent for in situ N-oxide reduction of pyridine-N-oxides. • As a substitute to bis(pinacolato) diboron for Miyaura borylation. |
