Synthesis of gemini surfactants from N-halosuccinimide-dimercaptoethane cohalogenation of olefinic fatty methyl esters
Olefinic fatty methyl esters (undec-10-enoate (1), octadec-Z,9-enoate (2), methyl 12-hydroxyoctadec-Z,9-enoate (3)), on reaction with N-halosuccinimides (4 and 5), i.e., N-bromosuccinimide (NBS, 4) or N-chlorosuccinimide (NCS, 5), and dimercaptoethane (6) in diethylether gave the gemini surfactants (beta,beta'-dibromodithioethers) (7-12).
