Synthesis and Reactivity of Heteroleptic Ga-P-C Allyl Cation Analogues.

ABSTRACT: Oxidative addition of cyclic alkyl(amino)carbene-coordinated phosphinidenes (^Me cAAC)PX to LGa affords gallium-coordinated phosphinidenes LGa(X)-P(^Me cAAC) (L=HC[C(Me)N(2,6-i-Pr₂ C₆ H₃ )]₂ ; X=Cl 1, Br 2), which react with NaBAr^F ₄ and LiAl(OR^F )₄ to [LGaP(^Me cAAC)][An] (An=B(C₆ H₃ (CF₃ )₂ )₄ 3, B(C₆ F₅ )₄ 4, Al(OC(CF₃ )₃ )₄ 5). The cations in 3-5 show substantial Ga-P double bond character and represent heteronuclear analogues of allyl cations according to quantum chemical calculations.
