Hydrosilylation reaction of hexafluoro-2-butyne 1 (HFB) with various silanes in the presence of a catalytic amount of transition-metal-catalysts was investigated. The reaction of HFB gave the corresponding bis(trifluoromethyl)containing vinylsilanes in an excellent regioselective manner in high yields. Treatment of the resulting vinylsilanes with various aldehydes and ketones in the presence of fluoride ion sources afforded the coupling products in moderate yields.

Page/Page column 4, (2010/07/04)
Disclosed is a process for the preparation of fluorine-containing olefins comprising contacting a chlorofluoroalkene with hydrogen in the presence of a catalyst at a temperature sufficient to cause replacement of the chlorine substituents of the chlorofluoroalkene with hydrogen to produce a fluorine-containing olefin, wherein said catalyst is a composition comprising chromium, nickel and optionally an alkali metal selected from potassium and cesium. Also disclosed are catalyst compositions for the hydrodechlorination of chlorofluoroalkenes comprising copper, nickel, and an alkali metal selected from potassium and cesium, and methods of making such catalysts.
