摘要

The rearrangement of 5-phenyl-1, 1, 1-trifluoro-2-(trifluoromethyl) pent-2-ene to 5-phenyl-1, 1, 1-trifluoro-2-(trifluoromethyl) pent-3-ene has been studied by 19 F NMR in dimethylsulphoxide (DMSO). This isomerisation is catalysed by a base such as triethylamine. It is apparent that the olefin is more stable when the two trifluoromethyl groups are placed on a saturated carbon rather than on a vinylic carbon. In the isomerisation ...
