methane, (dioxidosulfanyl)trifluoro-, copper(2+) salt - Reference Information
| Introduction | Copper trifluoromethanesulfonate (Ⅱ) is a catalyst, and it has been reported in the literature that it can be used to synthesize ketal. With the rapid development of chemical industry, the variety and demand of ketal are increasing. Ketals are a class of intermediates that can be used in the carbonyl protection of organic compounds or in the pharmaceutical industry, and even as special reaction solvents. Copper trifluoromethanesulfonate (Ⅱ) can be supported on a specific rod-shaped mesoporous silica carrier. On the one hand, the supported copper trifluoromethanesulfonate (Ⅱ) catalyst has a high activity in catalyzing the ketal reaction, and the supported copper trifluoromethanesulfonate (Ⅱ) catalyst has a high activity in catalyzing the ketal reaction when used repeatedly, so that the supported copper trifluoromethanesulfonate (Ⅱ) catalyst is recovered and recycled. |
| Uses | Coupling reaction catalyst with oxidation characteristics; Halo addition reaction catalyst; Alcohol dehydration reaction catalyst. Effectively catalyze the addition of trimethylsilane cyano to carbonyl compounds. |
