Synthesis and characterization of some thioether compounds by thiol-ene click chemistry

Abstract

   In this study, some thioether compounds were prepared by thiol-ene click reaction using cheap starting materials from natural source or plastic waste such as limonene from orange peel, and styrene by thermal degradation (cracking) of plastic waste like spoon and fork plastic, and different reaction conditions were achieved, some starting material did not need any catalyst or heat like limonene reacts with thioglycolic acid to give 2-(4-methylcyclohex-3-en-1-yl)propyl)thio)acetic acid , where the reaction was exothermic and very fast, while the styrene need the catalyst such as water or glycerol to start the reaction with thioglycolic acid through nucleophilic addition to give 2-(phenethylthio)acetic acid . The synthesized thioether compounds were prepared in high yield through anti-Markonickov rule at room temperature  and diagnosed by FT- IR and H-NMR .
