Solvent‐Dependent Oxidative Addition and Reductive Elimination of H(2) Across a Gallium‐Zinc Bond

H(2) adds reversibly across the metal‐metal bond of [(BDI)Ga(H)−Zn(tmeda)(thf)][BAr(4) (F)] (BDI=[HC{C(CH(3))N(2,6‐iPr(2)‐C(6)H(3))}(2)](−), TMEDA=N,N,N′,N′‐tetramethylethylenediamine, BAr(4) (F−)=[B(C(6)H(3)‐3,5‐(CF(3))(2))(4)](−)). Due to the stabilising effect of solvent coordination, hydrogenati...

Descripción
Sumario:H(2) adds reversibly across the metal‐metal bond of [(BDI)Ga(H)−Zn(tmeda)(thf)][BAr(4) (F)] (BDI=[HC{C(CH(3))N(2,6‐iPr(2)‐C(6)H(3))}(2)](−), TMEDA=N,N,N′,N′‐tetramethylethylenediamine, BAr(4) (F−)=[B(C(6)H(3)‐3,5‐(CF(3))(2))(4)](−)). Due to the stabilising effect of solvent coordination, hydrogenation products [(BDI)GaH(2)] and [(tmeda)ZnH(thf)][BAr(4) (F)] are favoured in THF solution, but THF‐free mixtures of [(BDI)GaH(2)] and [(tmeda)ZnH(OEt(2))][BAr(4) (F)] are predisposed towards entropically driven dehydrogenation to [(BDI)Ga(H)−Zn(tmeda)][BAr(4) (F)] in fluorobenzene solution.
