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

A metal-free addition of unactivated alkyl bromides to quinoxalin-2(1H)-ones is described. This method enables the construction valuable 3,3-disubstituted dihydroquinoxalin-2(1H)-ones bearing quaternary carbon centers under mild, visible-light photoredox catalysis. High functional group tolerance observed in both quinoxalinone and bromide partners. The ability scale up this was demonstrated photo-flow conditions enable gram-scale synthesis.
The coordination of small molecules to low valent titanium complexes provides a powerful platform for the transformation challenging substrates either through PCET reactions or bond-weakening induced by π-back donation electrons from Ti.
