    Abstract: The invention comprises carborane polyols of the formula wherein R1 and R2 are hydrocarbon groups and preferably lower alkyl groups having from 1 to 4 carbon atoms, or hydrogen, R3 is such a hydrocarbon group, or hydrogen, or a polyol group of the formula wherein R4 and R5 are hydrocarbon groups, preferably lower alkyl groups having from 1 to 4 carbon atoms, or hydrogen, and #q is C2H10B10. The compounds may be made by reacting an epoxy alkenylcarborane of the formula with water in the presence of an acid catalyst, such as sulphuric acid, or Lewis acids such as boron trifluoride. Diepoxy - dialkenyl - carboranes can similarly be converted to carborane polyols. The epoxyalkenylcarboranes may be made by reacting an alkenyl carborane in an inert solvent medium with hydrogen peroxide and trifluoroacetic anhydride.
