Electrophilic Fluorophosphonium Cations in Frustrated Lewis Pair Hydrogen Activation and Catalytic Hydrogenation of Olefins

Thorsten Vom Stein et al. Angew Chem Int Ed Engl. .

Abstract

The combination of phosphorus(V)-based Lewis acids with diaryl amines and diaryl silylamines promotes reversible activation of dihydrogen and can be further exploited in metal-free catalytic olefin hydrogenation. Combined experimental and density functional theory (DFT) studies suggest a frustrated Lewis pair type activation mechanism.

Keywords: Lewis acids; alkenes; frustrated Lewis pairs; hydrogenation; phosphorus.
