A new method for the synthesis of 2-aryl-1-sulfonylpyrrolidines I (R = Me, Et, Ph, p-tolyl; R¹ = 5-chloro-2,4-dihydroxyphenyl, 2-hydroxynaphthalen-1-yl, 2,7-dihydroxynaphthalen-1-yl) on the basis of reactions between various phenols ArH and N-(4,4-diethoxybutyl)sulfonamides RS(O)₂NH(CH₂)₃CH(OEt)₂ in the presence of trifluoroacetic acid has been developed. This study involved multiple reactions and reactants, such as 4-Chlororesorcinol (cas: 95-88-5Name: 4-Chlororesorcinol).

4-Chlororesorcinol (cas: 95-88-5) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Name: 4-Chlororesorcinol
