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.

金属催化的氯氟烃（C-Cl + H2 -> C-H + HCl）的加氢脱氯是制备氢氟烃（HFC）的有用反应，氢氟烃可用作制冷剂、发泡剂和具有低臭氧消耗潜势的溶剂。最近的工作表明，某些不饱和氢氟碳化合物的全球升温潜能值也较低，但需要更有效的商业合成。在这个项目中，我们将测试催化剂的选择性还原偶联的C2氯碳化合物的C4不饱和氯碳化合物，作为一个中间体，以一个有价值的不饱和氢氟碳化合物。将采用快速通量催化剂测试和机理研究的结合，以确定工业合作伙伴可以使用的最佳催化剂系统。
