Abstrakt: Irradiation of Cp 2 TiCl 2 with green light leads to electronically excited [Cp 2 TiCl 2 ]*. This complex constitutes an efficient photoredox catalyst for the reduction of epoxides and for 5-exo cyclizations of suitably unsaturated epoxides. To the best of our knowledge, our system is the first example of a molecular titanium photoredox catalyst.
