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 H-2 and C-H bonds.
