We report on the reactivity of a
boryloxy-functionalized phosphaalkyne,
[B]OCP ([B] = N,N′-bis(2,6-diisopropylphenyl)-2,3-dihydro-1H-1,3,2-diazaboryl), toward a series of tungsten(0) reagents
to afford the novel complex W(η2-PCO[B])3(CO). As with related organometallic complexes of alkynes, the C3v symmetry adopted by this
complex imposes that, of the three coordinated phosphaalkyne ligands,
two act as four-electron donors while the remaining species donates
two electrons to the tungsten metal center. W(η2-PCO[B])3(CO) readily loses carbon monoxide in the presence of Lewis
bases to afford W(η2-PCO[B])3(L) (where
L = PMe3, CNtBu).
