Synthesis of Acyclic, Symmetrical 3,3'-Allyl Dithioethers, from the Alkylation of 3-Mercapto-2-mercaptomethyIprop-l -ene in the Presence of Sodium Hydride

摘要

A novel method where 3,3'-allyl dithioethers have been prepared from 3-mercapto-2-mercaptomethylprop-1 -ene and two mol equivalent of alkyl halide in the presence of two mol equivalent of sodium hydride has been developed. Using this method, bisepoxide, 2,2'-(2-methylenepropane-l,3-diyl)bis(sulfanediyl)bis(methylene)dioxirane (8) has been synthesized from epichlorohydrin, whereas potassium carbonate was unable to deliver this product. These 3,3'-allyl dithioethers can be utilized either as monomers, or with further chemical reactions transformed into more complex monomers, for photoplastic polymer networks.
