RESEARCH IN HIGH-ENERGY OXIDIZERS

The methoxides (F2N)2CFOK and (F2N)3COK reacted with FNO2 to yield N2F4, FNO, NO2, and CoF2. It was found that (F2N)3COK is a very sensitive compound when dry. A base catalyzed decomposition of F2NCOF to COF2 and N2F2 has been observed, and postulated to proceed through esters of F2NCOF. Evidence fo...

Description
Summary:The methoxides (F2N)2CFOK and (F2N)3COK reacted with FNO2 to yield N2F4, FNO, NO2, and CoF2. It was found that (F2N)3COK is a very sensitive compound when dry. A base catalyzed decomposition of F2NCOF to COF2 and N2F2 has been observed, and postulated to proceed through esters of F2NCOF. Evidence for the formation of these esters has been obtained for the bases tert-butoxide, K2CO3, K2C2O6, and KOCN. The reaction with K2CO3 was examined by n.m.r. and evidence was found for the presence of F2NCF2OK,(F2N)2CFOK and an unknown that may be the postulated carbamate. Electrochemical studies of solutions of F2NCF2OK have been initiated with a view toward utilizing this technique for the synthesis of new oxidizers. Preliminary work has been carried out in acetonitrile saturated with KPF6 at-40 C, and indicates that F2NCF2OK was oxidized as anticipated. Attempts at the synthesis of new carbonate intermediates for the eventual synthesis of FC(OF)3 are described. The flow reaction of hot CF3OF with a mixture of CO and O2 has yielded COF2, CO2, F2C2O4 and an unidentified substance. During the preparation of F2C2O4 a new compound was concomitantly formed and thought to be F2C2O6. The reactions of FCO2NF2 with NF2CF2OK under a variety of conditions lead to the formation of N2F4, COF2 and CO2. The fluorination of F2NCF2OK with IF7 in the presence of N2F4 was examined in some detail, and evidence was found for the possible formation of F2NOCF2NF2. (Author)
