A biradical cyclic alkyl(amino)carbene-stabilised 9,10-diboraanthracene (DBA) activates small molecules such as hydrogen, phenyl azide or TEMPO (2,2,6,6-tetramethylpiperidin-1-oxyl) across its two boron atoms, while reactions with [(MeCN) 3 M(CO) 3 ] (M = Cr, Mo, W) yield the first half-sandwich DBA complexes of the form [(η 6 -DBA)M(CO) 3 ].
