title: Transition-metal-catalyzed synthesis of diboranes(4).
abstract: 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).
