Catalyzed reductive coupling of CF3CCl3

金属催化的氯氟烃(C-Cl+H2-&GT；C-H+HCl)加氢脱氯反应是制备氢氟烃(HFC)的有用反应，可用作制冷剂、发泡剂和低臭氧消耗潜力的溶剂。最近的工作表明，选定的不饱和氢氟碳化物也表现出较低的全球变暖潜力，但需要更有效的商业合成。在这个项目中，我们将测试用于将C2氯碳选择性还原偶联为C4不饱和氯碳的催化剂，C4不饱和氯碳用作有价值的不饱和氢氟碳化物的中间体。将采用快速生产能力催化剂测试和机理研究相结合的方法，以确定最优的催化剂系统，然后可供工业合作伙伴使用。

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.
