    Abstract: A solid nitrating reagent comprises either a montmorillonite clay or a zeolite material incorporating an amount of gaseous dinitrogen pentoxide. The clay material can be type K10 and suitable zeolites include those designated ZSM-5, zeolite beta, zeolite F720 and zeolite F780 (all H form). The reagent is conveniently prepared by exposing a sample of the montmorillonite clay or zeolite material to gaseous dinitrogen pentoxide contained in a stream of ozonised oxygen at a sub-ambient temperature while agitating the clay or zeolite material. The temperature is in the range of -60 to -20 DEG C. In use the reagent is contacted with a substance to be nitrated in an inert solvent such as hexane or a perfluorocarbon at a temperature of -20 to 15 DEG C, preferably around 0 DEG C. Suitable substrates include alcohols, O-silyl ethers and silylamines.
