Abstract

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.
