The effect of high pressure was studied on the rate and direction of the homolytic transformations of 1,3-oxathiolanes.Pressure reduces the rate of the transformation of 2-methyl- and 2-isopropyl-1,3-oxathiolanes to ethyl and 2-chloroethyl thoiacylates in the presence of CCl4 to a greater extent than the initiation rate in the system.The selectivity of the formation of the reaction product which is formed more rapidly at normal pressure is increased in the competing homolytic transformations of 2-methyl- and 2-isopropyl-1,3-oxathiolanes to the corresponding ethyl thioacylates with increasing pressure.The yield of the cyclic adduct, 2-methyl-2-hexyl-1,3-oxathiolane, relative to that of linear octyl thioacetate is increased in the homolytic addition of 2-methyl-1,3-oxathiolane to 1-hexane with increasing pressure.

In the presence of tert-butyl peroxide at 150 deg C 1,3-dithiolane and 2-methyl-1,3-dithiolane add to 1-hexene, forming 2-hexyl-1,3-dithiolane and 2-methyl-2-hexyl-1,3-dithiolane respectively.Under these conditions 1,3-oxathiolane and 2-methyl-1,3-oxathiolane form 2-hexyl-1,3-oxathiolane and octyl thioformate and 2-methyl-2-hexyl-1,3-oxathiolane and octyl thioacetate respectively.
