PhSe(O)OH/Al(NO₃)₃-Catalyzed selectivity controllable oxidation of sulphide owing to the synergistic effect of Se, Al³⁺and nitrate

Abstract

Selective oxidation of sulphides to produce sulfoxides or sulphones is a key technique in industry. In this paper, we found that, the reaction could be catalyzed by the PhSe(O)OH/Al(NO3)3 system...

Ru@C as a safety mask of RuO4@C for selective catalytic oxidation of alkynyl sulfurs to prepare alkynylsulfones

“…Conventional methods 16–21 for the synthesis of alkynylsulfones can be summarized in several ways, and their salient features are briefly described in Scheme 2. The preparation of alkynylsulfones by their corresponding alkynyl sulfide oxidation was the most commonly reported method.…”

“…Once it completes its service, it can leave the molecule through oxidation, reduction, coupling, elimination, and other methods so as to achieve a traceless synthesis of the target molecule. 15 Conventional methods [16][17][18][19][20][21] for the synthesis of alkynylsulfones can be summarized in several ways, and their salient features are briefly described in Scheme 2. The preparation of alkynylsulfones by their corresponding alkynyl sulfide oxidation was the most commonly reported method.…”
