The diboranes(4) bis(catecholato)diborane (B 2 Cat 2 ) and bis(pinacolato)diborane (B 2 Pin 2 ) are important precursors for organoboronic esters, which are versatile reagents for the formation of carbon–carbon bonds. A new catalytic synthesis for these compounds starts from catecholborane or pinacolborane and gives the dehydrocoupling products B 2 Cat 2 and B 2 Pin 2 with turnover numbers of up to 11 600 (see scheme).
