Firoozi, Somayeh; Hosseini-Sarvari, Mona published their research in Journal of Organic Chemistry in 2021. The article was titled 《Nanosized CdS as a Reusable Photocatalyst: The Study of Different Reaction Pathways between Tertiary Amines and Aryl Sulfonyl Chlorides through Visible-Light-Induced N-Dealkylation and C-H Activation Processes》.Name: 4-Chlorobenzenesulfonyl chloride The article contains the following contents:
The final products of the reaction of sulfonyl chlorides and tertiary amines in the presence of cadmium sulfide nanoparticles under visible light irradiation are highly dependent on the applied reaction conditions. Interestingly, with the change of a reaction condition, different pathways were conducted (visible-light-induced N-dealkylation or sp3 and sp2 C-H activation) that lead to different products such as secondary amines and various sulfonyl compounds Remarkably, all of these reactions were performed under visible light irradiation and an air atm. without any additive or oxidant in benign solvents or under solvent-free conditions. During this study, the CdS nanoparticles as affordable, heterogeneous, and recyclable photocatalysts were designed, successfully synthesized, and fully characterized and applied for these protocols. During these studies, intermediates resulting from the oxidation of tertiary amines are trapped during the photoinduced electron transfer (PET) process. The reaction was carried out efficiently with a variety of substrates to give the corresponding products at relatively short times in good to excellent yields in parallel with the use of the visible light irradiation as a renewable energy source. Most of these processes are novel or are superior in terms of cost effectiveness, safety, and simplicity to published reports. In addition to this study using 4-Chlorobenzenesulfonyl chloride, there are many other studies that have used 4-Chlorobenzenesulfonyl chloride(cas: 98-60-2Name: 4-Chlorobenzenesulfonyl chloride) was used in this study.
4-Chlorobenzenesulfonyl chloride(cas: 98-60-2) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Name: 4-Chlorobenzenesulfonyl chloride
