    摘要: Novel nonionic perfluoroalkylthioglycosides of the formula R f -E-S-saccharide are described, wherein R f is a straight or branched chain perfluoroalkyl of 1 to 18 carbon atoms or said perfluoroalkyl substituted by perfluoroalkoxy of 2 to 6 carbon atoms, E is a connecting group, and the saccharide is a mono-, di-, or higher oligosaccharide comprising 1 to 30 units of 5, 6, or 7 carbon-membered sugars. They can be used as surfactants.
