68986-76-5 - Reference Information
| Introduction | copper (I) thiophene-2-carboxylate is an organic intermediate, it can be obtained by reacting 2-thiophenecarboxylic acid with Cu2O. It has been reported in the literature to be useful in the preparation of 4-allylacetate substituted N-sulfonyl 1,2, 3-triazoles. |
| Use | copper (II) thiophene-2-carboxylate is an organo-copper catalyst, there is some damage to the respiratory system and skin. It can be prepared from thiophene-2-carboxylic acid in one step. |
| preparation | 2-thiophenecarboxylic acid (100g, 780 mmol), Cu2O (28g, 196 mmol) and toluene (300 mL) was added to a 500 mL three-necked round bottom flask. The flask was charged with Dean-Stark and a condenser. The mixture was then refluxed for 3 days with azeotropic removal of water. The tan suspension was then cooled to -60°C and the product was collected on a glass sinter funnel (D-frit). Under a nitrogen stream, the filter cake was washed with 300 mL of methanol and then with Et2O until the filtrate was colorless and then with 75 mL of hexane. The product was dried under a stream of N2 and then transferred to a flask and dried under vacuum to give Copper (I) thiophene-2-carboxylate (70g, 94%) as a light brown powder. |
