Irradiation of Cp2TiCl2 with green light leads to electronically excited [Cp2TiCl2]*. 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.

We describe a regiodivergent synthesis of pseudo‐C2‐symmetrical and pseudo‐meso bis‐indoline scaffolds from norbornadiene and substituted o‐iodo‐anilines. The Pd(0)/Josiphos system enables the highly regioselective catalyst controlled carboaminations required for the two step synthesis of the scaffolds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
