Abstract

Scheme A Methoxyphenyl alkyl sulphides can be obtained by the reac-tion of the chlorophenyl alkyl sulphides with sodium methox--ide. in these cases, displacement of the chlorine atom is in competition with the nucleophilic aliphatic substitution at the methylthio group or with the elimination reaction at the iso--propylthio group so that some p- chlorothiophenol is also obtained from the reactions of p-chlorophenyl methyl sulphide ...
