The chemical or electrochemical reduction CF3Co(CO)3 PPh3 is a two-electron process involving heterolytic cobalt-carbon bond cleavage to yield trifluoromethyl anion and cobalt carbonyl anions. The trifluoromethyl anion rapidly decomposes to fluoride and difluorocarbene. This carbene may dimerize to form C2F4. The unstable fluoro carbene can also be trapped by cyclohexene.Though this would create some problems with shimming in the NMR, it allowed the reduction of other organic products to fluoride ions. As expected, the final 19F NMR spectrum did not show a good S/N ratio. Since fluoride anions are solubleanbsp;...
