S. Bergeron et al., FLUORINATED KETENE DITHIOACETALS .3. A RADICAL ENTRY TO ALPHA-PERFLUOROALKYL KETENE DITHIOACETALS - APPLICATION TO SUGAR-DERIVATIVES, Tetrahedron letters, 35(13), 1994, pp. 1985-1988
Alpha-perfluoroalkyl ketene dithioacetals were synthesized by radical
perfluoroalkylation of ketene dithioacetals with perfluoroalkyl iodide
and sodium dithionite in a basic medium. Application to sugar derived
ketene dithioacetals gave results depending strongly on the sugar str
ucture.
