The synergistic effect of photocatalysis and proton-reduction catalysis enables an unprecedented dehydrogenative oxygenation of β-alkyl styrenes and their derivatives with water under external-oxidant-free conditions. This dual catalytic system possesses the single anti-Markovnikov selectivity due to the property of the visible-light-induced alkene radical cation intermediate.

In this reaction, H2O is not the terminal oxidant. External Oxidants-Free Anti-Markovnikov Oxidation of β-Alkyl Styrenes with Hydrogen Evolution as title would be better.
