Polystyrene??Supported N??Heterocyclic Carbene–Silver Complexes as Robust and Efficient Catalysts for the Reaction of Carbon Dioxide and Propargylic Alcohols
Abstract Three polystyrene-supported N-heterocyclic carbene–silver complexes [PS-NHC- Ag (I)] and a polystyrene-supported N-heterocyclic carbene–copper complex [PS-NHC-Cu (I)] catalyst were synthesized and characterized by elemental analysis, Fourier transform infrared spectroscopy, inductively coupled plasma-atom emission spectrometer, thermogravimetric analysis and scanning electron micrographs. The catalytic activity of the ...
