Photoexcited electron-hole pairs on a semiconductor surface can engage in redox reactions with two different substrates. Similar to conventional electrosynthesis, the primary redox intermediates afford only separate oxidized and reduced products or, more rarely, combine to one addition product. Here

Nicewicz Photoredox Catalysts for Anti-Markovnikov Alkene Hydrofunctionalization

While Markovnikov alkene reactivity is very well developed and utilized commonly in the synthesis of commodity and research chemicals, catalytic access to the anti-Markovnikov-selective adducts is a much less-developed endeavor.
