Thermomorphic polyethylene-supported olefin metathesis catalysts. Academic Article

abstract

• The preparation of polyethylene-oligomer (PE(olig))-supported N-heterocyclic carbene ligands (NHCs) and their Ru complexes is described. These complexes are structurally analogous to their low molecular weight counterparts and can serve as thermomorphic, recoverable/recyclable ring-closing metathesis (RCM) catalysts. Because of the insolubility of PE(olig)-supported species at 25 C, such complexes can perform homogeneous RCM reactions at 65 C and, upon cooling, precipitate as solids. This allows for their quantitative separation from solutions of products.
