| titleOfInvention | N-heterocyclic carbene carboxylate bidentate ligand, bidentate ruthenium complex, preparation methods and application of N-heterocyclic carbene carboxylate bidentate ligand and bidentate ruthenium complex in catalysis of carboxylic acid-alkyne addition |
| abstract | The invention discloses a nitrogen heterocyclic carbene carboxylate radical bidentate ligand and bidentate ruthenium complex, a preparation method and application thereof in catalyzing carboxylic acid-alkyne addition, wherein imidazole and derivatives thereof and methyl chloroacetate are used as raw materials to synthesize the bidentate ligand containing imidazolium radical, and the nitrogen heterocyclic carbene chelate ligand is subjected to transfer metallization to obtain the nitrogen heterocyclic carbene carboxylate radical bidentate ruthenium complex; the nitrogen heterocyclic carbene carboxylate bidentate ruthenium complex is used as a catalyst to catalyze the intramolecular or intermolecular carboxylic acid-alkyne addition reaction. The complex provided by the invention has good carboxylic acid-alkyne addition reaction catalytic activity, especially intramolecular addition reaction, milder temperature and higher catalytic yield. The first time, the mesoionic azacyclo-carbene-ruthenium complex is used for catalyzing the addition reaction of carboxylic acid-alkyne. |
