• One-pot odorless thioarylation of alkyl substrates using thiourea as the sulfur surrogate is achieved.
• The reactions are performed in polyethylene glycol (PEG200) as an eco-friendly media.
• The protocol is applicable for scaled-up reactions.
• The desired aryl alkyl sulfides are produced in good to excellent yields.
In this study, we have presented a useful catalytic application of copper(I) iodide for one pot odor-free generation of unsymmetrical aryl alkyl thioethers. The process proceeds by the reaction of phenolic esters such as acetates, triflates, tosylates and phosphonates with benzyl, n-octyl, cyclohexyl, cyclopentyl, n-hexyl and n-butyl iodides, bromides, chlorides and tosylates in wet polyethylene glycol (PEG 200) by using thiourea as the sulfur source under homogeneous conditions. The method is applicable for the gram-scale preparation of the desired alkyl aryl thioethers.
