  1,2-Diphosphonium Dication: A Strong P-Based Lewis Acid in Frustrated Lewis Pair (FLP)-Activations of B–H, Si–H, C–H, and H–H Bonds

  摘要：

  A highly Lewis acidic diphosphonium dication [(C10H6)(Ph2P)2](2+) (1), in combination with a Lewis basic phosphine, acts as a purely phosphorus-based frustrated Lewis pair (FLP) and abstracts hydride from [HB(C6F5)3](-) and Et3SiH demonstrating the remarkable hydridophilicity of 1. The P-based FLP is also shown to activate H2 and C-H bonds.

  The readily prepared borenium salt [(IiPr(2))(BC(8)H(14))][B(C(6)F(5))(4)] (2) [IiPr(2) = C(3)H(2)(NiPr)(2)] is shown to activate H(2) heterolytically in the presence of tBu(3)P. Compound 2 also acts as a catalyst for the metal-free hydrogenation of imines and enamines at room temperature.

  The thermally robust silylium complex [iPr₃Si–PtBu₃]⁺[B(C₆F₅)₄]⁻ (1) activates H₂/D₂ at 90 °C (PhCl). However, experimental evidence and DFT calculations show no evidence for dissociation into the separated Lewis pair.

  热稳定的硅鎵复合物[iPr₃Si–PtBu₃]⁺[B(C₆F₅)₄]⁻（1）在90°C（苯）下激活H₂/D₂。然而，实验证据和DFT计算显示没有分解成分离的Lewis酸碱对的证据。
