Abstract
It is shown how the simple titanocene(III)-catalyzed reductive opening of epoxides has developed from a highly selective desymmetrizing opening of meso-epoxides. The combination of the origins of regioselectivity with atom-economic catalysis in single electron steps results in a highly selective regiodivergent epoxide opening (REO).
