Li, Peng; Herrmann, Wolfgang A.; Kuehn, Fritz E. published the artcile< Unsaturated NHC Complexes Immobilized by the Backbone: Synthesis and Application>, Application In Synthesis of 1003-21-0, the main research area is silica rhodium heterocyclic carbene complex catalyst styrene hydrogenation ethylbenzene.
The synthesis and an exemplary catalytic application of a SBA-15-supported rhodium-N-heterocyclic carbene (NHC) complex is reported. In contrast to the conventional method of immobilization of unsaturated NHC complexes, the rhodium-NHC compound described here is connected to the SBA-15 surface by a linker originating from the backbone of the unsaturated NHC ligand. The unique characteristics of the new immobilization mode enable the supported NHC complexes to maintain two unchanged “”wing-tip”” ligands. This method of immobilization of unsaturated NHC complexes provides a new way to maintain the original configuration of homogeneous NHC complexes in the heterogenized catalytic system. The immobilized rhodium-NHC catalyst is used in a hydrogenation reaction with styrene as substrate.
