Visible‐light‐mediated photogeneration of Cp 2 Ti III Cl has opened new avenues for titanium catalysis. The synergistic utilization of dual photoredox and Cp 2 Ti III Cl catalysis uses Hantzsch ester (HE) as an electron donor instead of traditional super‐stoichiometric metallic reductants. This new paradigm has found numerous applications in synthetic organic chemistry. The highly efficient photoinduced electron transfer process between light‐sensitive Cp 2 TiCl 2 and an excited photocatalyst is the key to the success of such a photocatalytic system and ensures overall catalyst turnover. Comparisons between the metal reduction approach and photo reduction approach have been made.
