项目摘要
This award by the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Russell P Hughes, Department of Chemistry, Dartmouth College, in fluorocarbon bond activation by transition metals. Hughes is developing novel catalytic routes to convert chlorofluorocarbons (CFCs) and perfluorocarbons (PFCs) to hydrofluorocarbons (HFCs). Aliphatic C-F bonds in fluoroalkyl groups bonded to a cationic iridium center undergo facile reaction with hydrogen gas under ambient conditions, resulting in the substitution of a C-H bond for the C-F bond. The fluoroalkyl groups may also react with methane to make a new carbon-carbon bond. By further study, the scope of these important reactions will be expanded to new substrates and catalysts. Perfluorocarbons and chlorofluorocarbons are industrially important chemicals used as refrigerants, foaming agents and solvents. However these compounds also are implicated in ozone depletion and global warming. Hydrofluorocarbons have many of the same useful properties, yet are more environmentally friendly. This research may lead to new useful HFCs as well as provide a new way to deactivate and recycle PFCs and CFCs.
该奖项由无机、生物无机和有机金属化学项目颁发,支持达特茅斯学院化学系拉塞尔·P·休斯在过渡金属激活氟碳键方面的研究。休斯正在开发新的催化途径,将氯氟烃(CFCs)和全氟碳化合物(pfc)转化为氢氟碳化合物(hfc)。氟烷基中与阳离子铱中心相连的脂肪族C-F键在环境条件下容易与氢气发生反应,导致C-H键取代C-F键。氟烷基也可以与甲烷反应生成新的碳-碳键。通过进一步的研究,这些重要反应的范围将扩大到新的底物和催化剂。全氟化碳和氯氟化碳是工业上重要的化学品,用作制冷剂、发泡剂和溶剂。然而,这些化合物也与臭氧消耗和全球变暖有关。氢氟碳化合物具有许多相同的有用特性,但更环保。这项研究可能会产生新的有用的氢氟碳化合物,并为全氟碳化合物和氟氯化碳的失活和回收提供新的途径。
