ADDITION AND SUBSTITUTION PRODUCTS OF OXYGEN FLUORIDES

A new type of highly colored deep-violet addition compounds of O2F2 was obtained. These compounds were formed by addition to ClF, BrF3 and SF4, under mild reaction conditions. They have a remarkable oxidizing power, even at very low temperatures. The O2F2 ClF reaction was studied extensively. Various combinations of the factors influencing the synthesis were investigated, and the yield was raised to 81 of the theoretical value. The investigation of the properties of the compound, with an elementary composition of O2ClF3, showed that it was contaminated only by ClF3, and stable at 195 K. It was kept at this temperature for over 9 months without any noticeable decomposition. The compound was soluble in liquid ClF3, ClF, O2F2 and HF, at 125 to 190 K., but was insoluble in liquid O2, O3, ClO3F, C3F8, NF3, CCl2F2 and CClF3 in the range of 90 to 160 K. When dissolved in anhydrous HF at -78 C it did not act as an electrolyte. The compound reacted vigorously with NH3, C2H6 and C2H4, even at 120 to 160 K.
