Investigation of a sulfonic acid functionalized ammonium-based permanganate hybrid as a sustainable oxidative catalyst for selective conversion of organic sulfides to sulfoxides

Permanganate hybrids of N , N ′-diethyldisulfoammonium ([DEDSA] + ) and 1,4-disulfopiperazinium ([DSPZ] 2+ ) cations were developed as recyclable oxidative catalysts for the selective conversion of organic sulfides to sulfoxides in dilute H 2 SO 4 solution.
