✦ Synopsis


Gss-phase stabilities of 1-aryl-2,2,2-trifluoroethyl cations were determined based on chloride-transfer equilibria. The substituent effect was analyzed based on the LArSR Eq., giving a remarkably high r of 1.53 and a p of -14.6. The previous study' has shown that the substituent effect for the gas-phase stabilities of 1-aryl-1-(trifluoromethyl)ethyl cations can be described excellently in terms of our LArSR equation (1)2 with an r of 1.40 and a p of -14.0. aAGo = p(a" + r AZ:) (I)

The kinetics of the gas-phase reaction of 2,2,2-trifluoroethyl iodide with hydrogen iodide has been studied over the temperature range of 525'K to 602Β°K and a tenfold variation in the ratio of CF3CHtI/HI. The experimental results are in good agreement with the expected free radical-mechanism: An an
