The reactions of C1 and C2 chlorohydrocarbons and chlorocarbons have been studied with the Lewis acid catalysts fluorinated gallium(III) oxide and fluorinated indium(III) oxide, respectively. Product analysis shows chlorine-for-fluorine exchange reactions together with the formation of 2-methylpropane and its chlorinated analogues 2-chloromethyl-1,3-dichloropropane and 2-chloromethyl-1,2,3-trichloropropane. Reactivities of the chlorohydrocarbon probe molecules show fluorinated gallium(III) oxide to be a stronger Lewis acid than fluorinated indium(III) oxide. The formation of the symmetrical butyl compounds is consistent with the generation of surface radical species and is also consistent with a 1,2-migration mechanism operating within radical moieties at the Lewis acid surface.

KINETICS OF THE TRANSFORMATION OF 5-R-5-CHLOROMETHYL-2-THIA-2-OXO-1,3-DIOXANES TO 1,3-DICHLORO-2-R-2-CHLOROMETHYLPROPANES

Investigation of the kinetics of the formation of 1,3-dichloro-2-R-2-chloromethylpropanes from 5-R-5-chloromethyl-2-thia-2-oxo-1,3-dioxane by the action of an equimolecular mixture of thionyl chloride and dimethylformamide (the Vilsmeier-Haack reagent) led to the conclusion that the low activation energies and the large negative entropy values indicate the participation of a stable intermediate in the investigated complex many-stage reaction.
