ABSTRACT:
Xanthate esters of the form: ##EQU1## where R is an alkyl function having at least one H in a position alpha to the R - O bond, (C).sub.n is a linear alkyl function either substituted or unsubstituted, with n = 1 - 3, X has a basicity greater than the >C = S function and comprises a C or S containing functional group having at least one double or triple bond to a hetero atom, the functional group being connected to (C).sub.n through C or S; are reacted with Lewis acids, either neat or in non-protonic non-aqueous solvents, to yield novel Lewis acid complexes of the esters. The Lewis acid -- xanthate ester complex is decomposed by admixture with water or a protonic non-aqueous solvent, e.g. methanol, ethanol, etc., glycol, cellosolve, liquid ammonia, lower alkyl primary or secondary amines, aniline, etc., to yield an unsaturated derivative of R.
