Catalytic reactions of dimethyl disulfide with thiophene and benzene

The gas-phase reaction of dimethyl disulfide with thiophene proceeds under the action of acid catalysts under atmospheric pressure at 160-350°C and a residence time of τ = 0.6-21 s to form thioalkylation and alkylation products. Dimethyl disulfide reacts with benzene to form only alkylation products. Catalysts containing both strong protic and Lewis acid sites, as well as basic sites of moderate strength, are the most active ones.

Reaction of dimethyl disulfide with thiophene under the action of highly siliceous zeolite at 180-350°C and contact time 0.6-14 s resulted in formation of thioalkylation products, 2-(methylsulfanyl)- and 2,5-bis(methylsulfanyl)thiophenes and also alkylate

The photostimulated reactions between benzenethiolate and 2-chloro-, 2-bromo-, 2-iodo-, and 3-bromothiophene in MeCN lead to rather complex product mixtures where the phenyl thienyl sulfide(ThSPh), the ipso-substitution product, represents the main component.The collected results agree well with the occurrence of an SRN1 chain pathway.As to the obtainable yield of sulfide, the main drawback is represented by the fragmentation into ThS- and Ph(radical) of the ThSPh radical anion, formeded either along the propagation cycle or by single-electron reduction of the sulfide itself.Optimization of the yield of ThSPh, although at the expense of the overall reaction rate, can be achieved by the employment of suitable electron acceptors.The overall reactivity orders (2-I > 2-Br > 2-Cl and 2-Br > 3-Br) are also discussed.
