The esterification reactions of tolylthiol ester with secondary or tertiary alcohols are approximately two times faster than those of benzenethiol ester with silver trifluoroacetate. These results indicate that alkyl substitution in para position of aryl group enhances the reactivity toward the thiophilic reagents
