SYNTHESIS OF HALOGENATED MONODISPERSED TELECHELIC OLIGOMERS .3. BISTELOMERIZATION OF ALLYL ACETATE WITH TELOGENS WHICH EXHIBIT ALPHA,OMEGA-DI(TRICHLOROMETHYLED) END GROUPS

The redox bistelomerization of allyl acetate with telogens which exhibit alpha, omega-di(trichloromethyled) end groups catalyzed by copper, iron salts, or a ruthenium complex led to monoadducts and telechelic oligomers. These diacetates were quantitatively changed into diols. Such compounds have been characterized by both H-1- and C-13-NMR. A reactivity series has been determined and shows that both end groups must be activated to obtain the expected telechelic products in satisfactory yields.
