photochemical activation of the π-bond system

Why is it important?

Highlights The light-driven radical capture mechanism solves the long-standing slow oxidative addition problem of copper catalysts. At higher oxidation state, iron metal acting as a of Lewis acid, and stimulating the π-bond activation reactions. The “super nucleophilic” Co(III)* complexes can generate the carbon centered radicals via homolytic Co-C bond cleavage. TBADT, a polyoxotungstate involved C-H bond activation via SH2 mechanism is irrespective of substrate redox potential. Manganese employed photochemical reactions mostly follow the atom transfer radical mechanism (ATRM).
