POLYMER-SUPPORTED PHOSPHORUS LIGANDS FOR CATALYSIS

摘要

Novel phosphine and phosphine oxide ligands are prepared using polymeric supports. These compounds can be easily cleaved from the support, and along with the corresponding supported compounds, used as ligands in the preparation of novel, metal-complexed catalysts. The ligands are obtained by combinatorial synthesis. A process for preparing coumarin by contacting salicylaldehyde with an acrylate is also provided.
