Gas phase ion chemistry of 2-fluoropropane by ion cyclotron resonance spectroscopy
The gas phase ion chemistry of 2-fluoropropane is reported. The parent ion fragments to yield (CH/sub 3/)/sub 2/CF/sup +/, CH/sub 3/CHF/sup +/, and CH/sub 2/CHF/sup +/ as the abundant primary ions, all of which react with the parent neutral by F/sup -/ transfer to yield (CH/sub 3/)/sub 2/CH/sup +/ (CH/sub 3/)/sub 2/CH/sup +/ in turn reacts with the parent neutral by H/sup -/ transfer to regenerate (CH/sub 3/)/sub 2/CF/sup +/, thus completing a chain reaction which leads to the conversion of 2-fluoropropane to a mixture of propane and 2,2-difluoropropane via ionic intermediates. This chain reaction is terminated by a slow condensation reaction of C/sub 3/H/sub 7//sup +/ with 2-fluoropropane to yield C/sub 6/H/sub 13//sup +/. A variety of trapped ion cyclotron resonance techniques, including in particular cyclotron resonance ion ejection methods, permits all of the rate constants for this reasonably complex reaction scheme to be extracted. 21 references, 2 figures, 3 tables.
