Synthesis and Separation of a Diastereomeric Sulfonium Ion by Capillary Zone Electrophoresis
Francisco A. Valenzuela, Thomas K. Green, and Darwin B. Dahl
Department of Chemistry, Western Kentucky University, Bowling Green, KY 42101

December 1998
Vol. 75 No. 12
p. 1590
Abstract
An undergraduate laboratory exercise utilizing capillary zone electrophoresis in the analysis of the student-synthesized sulfonium ion sec-butylmethyl-p-tolylsulfonium tetrafluoroborate is presented. The sulfonium ion contains two stereogenic centers and thereby yields four optical isomers. Sulfated cyclodextrin is used as the buffer modifier to achieve chiral separation. Additionally, the NMR spectrum for this compound is presented and discussed.
