FIELD-EFFECT IN ELECTROCHEMICAL REACTIVITY OF ALKYLARYLSELENIDES

The anchimeric assistance of some substituents bearing the carbonyl gr oup alters the nature of the potential-determining reaction of the cat ion radicals of alkylarylselenides,-instead of a charge-controlled fra gmentation of the first order characteristic for these kinds of partic les, the orbital-controlled second order disproportionation of dimeriz ation take place.
