Synthesis of F3ClO was attempted by reactions of ClF5 with yellow HgO and systems involving KNO3 and KClO4. No evidence of F3ClO was found. The reaction of ClF3 and O3 gave FClO2, ClO2, and unidentified compounds with IR bands at 5.1, 8.7, and 12.9 microns. CaClO2 and Cl2O were fluorinated under a variety of conditions. At -80 C in the presence of CsF, Cl2O reacted with F2 to give an unidentified compound which may be a new Cl-F-O species. The dissociation of the complex NF2OBF3Cl- was examined. The only Cl- containing product found was Cl2. FNO3 and the potassium-fluoride-difluorine complex were reacted in hope of forming F2ONO2. Products were N2F4, NO2, and FNO2, suggesting the initial formation of NO3 and NF2 radicals. Fluorination of BrF5 at low temperatures was attempted by electrical discharge techniques. No new BrF species were indicated. In an effort to synthesize NF2-substituted interhalogen compounds, ClF3, ClF5, and IF5 were reacted with HNF2. Various complexes of both ClF3 and HNF2 were explored as well. The major product was ClNF2 the absence of Cl2 and ClF strongly suggested NF2ClF2 as an intermediate. Synthesis of NF2ClO2 was attempted by reacting HNF2 with FClO2 as well as its BF3 complexes. In the absence of BF3, deflagrations occurred. In the presence of BF3, the principal N-containing product was NOBF4.
