Complexation of a boron atom by an N-heterocyclic carbene has been enlisted to make an assortment of unusual lowvalent boron compounds and rare boron-containing reactive intermediates including boryl radicals 3a] and borenium ions. Such species have interesting fundamental properties and are potentially useful reagents in organic synthesis, among other applications. Nucleophilic boron reagents are extremely rare. Recent reviews list only two characterized boryl anions. The… CONTINUE READING
