The Role of Outer-Sphere Surface Acidity in Alkene Epoxidation Catalyzed by Calixarene—Ti(IV) Complexes.

Cooperativity between Brønsted acidic defect sites on oxide surfaces and Lewis acid catalyst sites consisting of grafted calixarene—Ti(IV) complexes is investigated for controlling epoxidation catalysis. Materials are synthesized that, regardless of the surface or calixarene substituent, demonstrate...
