Abstract
The invention consists of the compounds of the formula ##EQU1## (hereinafter DE), wherein X is chlorine or bromine, A is a vicinal alkylene of from 2 to about 8 carbon atoms which may bear a phenyl, hydroxy, chlorine or bromine substituent and R.sub.1 is an alkylene of from 4 to about 7 carbon atoms, two terminal carbon atoms of which are joined to C' to form a carbocyclic group upon which X- and XAO- are vicinally substituted and m and n are independently 0 or 1. These compounds are prepared by reacting the halogen XX with a mixture of the appropriate vinyl R.sub.1 cycloalkene (hereinafter VCR.sub.1), and the epoxide AO. Such compounds are useful as solvents and as reactants in the production of cycloaliphatic polythiols which are useful in curing polyepoxide resins.
