Alkylation of disodium benzyl and disodium methyl isocyanurates with beta,beta'-dichlorodiethyl and beta,beta'-dibromodiethyl ethers was used to prepare 1-benzyl and 1-methyl 3,5-bis[2-(2-haloethoxy)ethyl] isocyanurates whose reaction with thiourea followed by hydrolysis gave the corresponding 1-alkyl 3,5-bis[2(2-mercaptoethoxy)ethyl] isocyanurates. 1-Benzyl and 1-methyl 3,5-bis[2-(2-chloroethyl)ethyl] isocyanurates were reacted with NaSCH2CH2OH to obtain the corresponding 1-alkyl 3,5-bis[2-(2-hydroxyethylthio)ethyl] isocyanurates. Treatment of the latter two esters with thionyl chloride gave 1-benzyl and 1-methyl 3,5-bis[2-(2-chloroethylthio)ethyl] isocyanurates, respectively.
