Reactions of TeF5OCl with Fluorocarbon Iodides and Synthesis of CF3OTeF5.
1990
Abstract The low temperature reaction of TeF 5 OCl with the fluorocarbon iodides, CF 3 I, C 2 F 5 I, n-C 3 F 7 I, and i-C 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 F 5 OTeF 5 and n- C 3 F 7 OTeF 5 , respectively. These reactions constitute a new synthesis of primary R f OTef 5 compounds. Attempts to extend this synthesis to secondary fluorocarbon iodides were unsuccessful.
