摘要

Radical chain processes occur in conjugate addition reactions of 2-cycloalkenones with t- Bu}-lglf,(t-Bu) 2CuLi or (t-Bu) 3ZnLi as judged by the relative reactivity of 2-cyclopentenone> 2-cyclohexenone and by the effect of CI-l2= CPh2 as a radical trap. On the other hand,(n-Bu) zCuLi or (I-Bu) 2Cu (CN) Li2 react by a mechanism involving preferential attack upon 2- cyclohexenone. Vinyl substitution reactions of PhCH= CHSO,, Ph and PhCECSO,, Ph, ...
