The low temperature reaction of TeF5OCl with the fluorocarbon iodides, CF3I, C2F5I, n-C3F7I, and i-C3F7I results in the formation of RfI(OTeF5)2 adducts.Except for the trifluoromethyl derivative these are stable, colorless compounds.The trifluoromethyl adduct decomposes above -78 deg C to give the previously unknown CF3OTeF5.The perfluoroethyl and n-propyl adducts decompose at 120 deg C or under UV radiation giving C2F5OTeF5 and n-C3F7OTeF5, respectively.These reactions constitute a new synthesis of primary RfOTeF5 compounds.Attempts to extend this synthesis to secondary fluorocarbon iodides were unsuccessful.
