Halogenated triphenylgallium and -indium in frustrated Lewis pair activations and hydrogenation catalysis.

ABSTRACT: The Lewis acids Ga(C₆F₅)₃, In(C₆F₅)₃ and Ga(C₆Cl₅)₃ are prepared and their Lewis acidity has been probed experimentally and computationally. The species Ga(C₆F₅)₃ and In(C₆F₅)₃ in conjunction with phosphine donors are shown to heterolytically split H₂ and catalyse the hydrogenation of an imine. In addition, frustrated Lewis pairs (FLPs) derived from Ga(C₆F₅)₃ and In(C₆F₅)₃ and phosphines react with diphenyldisulfide to phosphoniumgallates or indates of the form [tBu₃PSPh][PhSE(C₆F₅)₃] and [tBu
