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:
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.
