Abstract

Four tetraarylporphyrins bearing one n-C8F17 chain on each meso-aryl group have been synthesized. The Mn (III)-complexes of these new compounds (Mn-1-Mn-4) were used as catalysts in alkene epoxidations carried out under aqueous-organic biphasic conditions. High epoxide yields were obtained with catalysts in which, along with perfluoroalkyl chains, bulky substituents were present at appropriate positions. The expected general ...
