A metal-free method for the vicinal thiosulfonylation of unactivated alkenes R1CH=CHR (R = H, Me; R1 = benzyl, (trimethylsilyl)methyl, (prop-2-en-1-yloxy)methyl, 3-cyanopropyl, etc.; RR1 = -(CH2)4-, -(CH2)3-, -(CH2)2(O)-, etc.) with thiosulfonates R2S(O)2SR3 (R2 = Me, 4-methylphenyl, 4-fluorophenyl, thiophen-2-yl, etc.; R3 = Ph, Bu, 2-[methoxy(oxo)methane]phenyl, thiophen-2-yl, etc.) using 9-mesityl-10-methylacridinium perchlorate as photo-organocatalyst with visible-light irradiation has been developed. The method can be performed in di-Me carbonate under air at room temperature and features a broad functional group compatibility. Metrics indicate the green potential of the developed vs. the state-of-the-art methodologies. Mechanistic studies revealed no single electron transfer but involvement of an energy transfer from the excited photo-organocatalyst to thiosulfonate reactant, subsequently providing a sulfenyl and a sulfonyl radical via homolytic cleavage. In the experiment, the researchers used many compounds, for example, Thiophene-2-sulfonyl chloride(cas: 16629-19-9Application of 16629-19-9)
Thiophene-2-sulfonyl chloride(cas: 16629-19-9) is a member of sulfonyl chlorides. Sulfonyl chlorides are reactive sulfonic acid derivatives similar in properties and reactivity to acid chlorides of carboxylates. The sulfonic acid group, however, is a highly hindered molecule, containing a tetrahedral configuration of substituents. Application of 16629-19-9
