Together with this last rearrangedproduct, the ipso substitution derivative was also observed. Similar results were obtained in the PET reactions of 4d (R = t-Bu) with anions 2 and 3 under entrainment conditions with the enolate anion from cyclohexenone (5) or the tert-butoxide anion (6). From this novelrearrangement, and only under reductive conditions by PET reaction with anion 5, iodide 4d (R
