ABSTRACT:
The invention relates to 1-C-perfluoroalkyl glucosides consisting essentially of a monosaccharide having an anomeric carbon directly linked to a perfluoroalkyl radical and a hydroxyl group. These glycosides are prepared by a process comprising: (a) reacting an aldonolactone with a hydroxyl protecting group; (b) reacting the product of step (a) with a compound of formula R.sub.F -M in which R.sub.F represents a linear or branched perfluoroalkyl radical containing from 2 to 12 carbon atoms, and M represents Li or MgX, X being a halogen; and (c) liberating the hydroxyl group. The 1-C-perfluoroalkyl glycosides may be used as surfactants and as flame retardants.
