AuI/AuIII catalytic cycles can trigger three highly regioselective alkene difunctionalization processes that involve the formation of C(sp3)O, C(sp3)N, and C(sp3)C(sp2) bonds. The reaction can proceed by reductive elimination on the oxidized gold center with complete retention of the configuration or through two subsequent nucleophilic substitution reactions via an aziridine intermediate.
