Herein, authors reported a so far unprecedented Mn(OAc)3·2H2O-promoted homolytic aromatic sulfonation. The reaction was performed under mild conditions with K2S2O5 employed as a green sulfonating reagent. Various arenes were successfully converted into desired sulfonic acids or sulfonates in high efficiency. Preliminary mechanistic studies demonstrated that the present reaction proceeds via a homolytic aromatic substitution-type mechanism involving an SO3– radical. The combination of Mn(OAc)3·2H2O and HFIP plays a crucial role. This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8SDS of cas: 638-02-8).
2,5-Dimethylthiophene (cas: 638-02-8) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. It is also used in the manufacturing of dyes such as thioindigo.SDS of cas: 638-02-8
