Abstract The low temperature reaction of TeF 5 OCl with the fluorocarbon iodides, CF 3 I, C 2 F 5 I, nC 3 F 7 I, and iC 3 F 7 I results in the formation of R f I (OTeF 5) 2 adducts. Except for the trifluoromethyl derivative these are stable, colorless compounds. The trifluoromethyl adduct decomposes above− 78 C to give the previously unknown CF 3 OTeF 5. The perfluoroethyl and n-propyl adducts decompose at 120 C or under UV radiation giving C 2 ...
