An increase in the electron-withdrawing capacity of the radicals attached to the dithio ester group (C6H4NO2-p and CO2Me in comparison with Ph and Me) enhances the rate of cycloaddition of the corresponding allyl and benzyl dithiocarboxylates to activated acetylenes, leading to the formation of 2,2-disubstituted 1,3-dithiols.We studied the effect of the nature of the acetylene cycloaddend on the regioselectivity of the migration of the allyl group upon 1,3-dithiol formation in the case of the β,γ,γ-trichloroallyl ester of dithiobenzoic acid.
