Catalyzed reductive coupling of CF3CCl3

金属催化氯氟化碳的加氢脱氯（C-Cl + H2——> C-H + HCl）是制备氢氟碳化合物的有用反应，氢氟碳化合物可用作制冷剂、发泡剂和低臭氧消耗潜能值的溶剂。最近的工作表明，某些不饱和氢氟碳化合物也表现出较低的全球变暖潜能值，但需要更有效的商业合成。在本项目中，我们将测试C2氯碳与C4不饱和氯碳选择性还原偶联的催化剂，C4不饱和氯碳可作为有价值的不饱和氢氟烃的中间体。将采用快速通量催化剂测试和机理研究相结合的方法，以确定工业合作伙伴可以使用的最佳催化剂系统。

Metal-catalyzed hydrodechlorination of chlorofluorocarbons (C-Cl + H2 --> C-H + HCl) is a useful reaction for the preparation of hydrofluorocarbons (HFCs) that find use as refrigerants, blowing agents, and solvents with low ozone depletion potential. Recent work has shown that selected unsaturated HFCs also exhibit low global warming potential but more efficient commercial syntheses are required. In this project we will test catalysts for the selective reductive coupling of a C2 chlorocarbon to a C4 unsaturated chlorocarbon that serves as an intermediate to a valuable unsaturated HFC. A combination of rapid throughput catalyst testing and mechanistic studies will be employed in order to identify the optimum catalyst system that can then be utilized by the industrial partner.
