oxidation states (Fig. , right). This particular chemical behavior leads to the facile generation of alkylradical fragments through single-electron-transfer (SET) oxidative addition from precursors such as redoxactive esters (RAE) or Katritzky salts (KS). The recent years have witnessed significant efforts towards mimicking the redox behavior of transition metals by main-group elements. For instance, pnictogens can take part in SN2-type polar oxidative additions resulting in two-electron maneuvering throughout (n)/(n+2) redox catalytic cycles, emulating those of late transition metals (Fig. , left). However, the radicalactivation of redox-active electrophiles is often restricted to first-row transition metals, and examples by a well-defined main group-element complex are rare.
