REDOX TELOMERIZATION OF DIETHYL ALLYL AND VINYLPHOSPHONATES WITH HALO COMPOUNDS AS TELOGENS

Abstract

Using copper salts as catalyst, we have telomerized diethyl allyl- and vinylphosphonate monomers with several different halo compounds as telogens. There is a linear relationship between log yield (telogen reactivity) and the [sgrave]∗ Taft constant of the R group in RCCl₃ as telogen. Using this relation, we have determined the values of the [sgrave]∗ constant for some other halo compounds and have established a classification of these telogens. We have likewise determined the structure of telomers formed with copper and iron salts as initiators for both monomers.
