Heterogeneous Catalysis by Frustrated Lewis Pairs

Abstract

Frustrated Lewis pairs (FLPs)Frustrated Lewis pair (FLP), featuring reactive Lewis acidLewis acid and Lewis baseLewis base sites that can cooperatively activate small molecules, have been exploited in a wide range of homogeneous catalytic reactions since their inception in 2006. However, it is only recently that the tenets of FLPFrustrated Lewis pair (FLP) chemistry have been used to develop heterogeneous catalysts, which are advantageous due to their ease of separation from reaction mixtures and the recyclability of the catalyst. This chapter outlines the many different approaches that research groups around the world have taken to synthesise and utilise semi-immobilisedSemi-immobilised or fully immobilised (solid-state) FLPFrustrated Lewis pair (FLP) catalysts. This includes supporting the Lewis acidLewis acid and/or base components on or within a whole host of different materials, including silicaSilica, zeolitesZeolite, metal-organic frameworks (MOFs), polyoxometalate clustersPolyoxometalate cluster, metal oxidesMetal oxide, grapheneGraphene and hexagonal boron nitrideHexagonal boron nitride.
