✦ Synopsis

Simple protonic superacid anhydrous hydrogen fluoride (aHF) and its use as solvent in reactions with high-oxidation-state materials is described. A general scheme for an acid-base dependence of the formation of fluorocations, binary compounds or fluoroanions is exemplified by the syntheses of complex high-oxidationstate fluoroanions in a basic aHF medium (e.g. AgFi, NiFz-), polymeric binary fluorides in neutral aHF medium (e.g. AgF,, NiF,J and cationic species in acidic aHF medium (e.g. Ag(III)(,,,,), Ni(IV)(,,,,). Cationic 4gW1)~,1,~ and NW) (sOIV) species are the strongest known oxidants and could surpass even KrF' salts. 0 Academic des Sciences/Elsevier, Paris
