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-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.
