Cover Story: Polyether amines are versatile compounds characterized by a flexible structure of polyoxypropylene and polyoxyethylene backbones with amine groups at each end. This study demonstrates the innovative use of polyether amine as a recyclable catalyst for the aerobic oxidation of thiophenols, leading to the synthesis of disulfides. In contrast to known methods for thiol oxidation, this polyether amine-based catalytic process eliminates the need for expensive stoichiometric oxidants and minimizes the formation of over-oxidized by-products. A remarkable yield of over 96% was achieved for all 16 test substrates, encompassing a diverse range of functional groups under catalytic aerobic oxidation conditions, using just 0.5% of polyether amine as the catalyst. View this paper
