Abstract

Metal migration reactions through CÀH bond activation, 1, 4-migrations in particular, have attracted significant attention in organorhodium and organopalladium chemistry not only as mechanistically intriguing processes but also as entries to novel remote CÀH bond functionalization reactions.[1–3] After the first observation of 1, 4-rhodium migration in the reaction of an arylboronic acid with norbornene by Miura et al.,[4] Hayashi and co-workers ...
