Polynitrogen Chemistry
Abstract
The novel Ns +HF2 salt was prepared and serves as a useful reagent for the preparation of other N5 + salts. The reactions of NF4+ and N2F3+ with HN3 were studied. WHile NF4+ acted only as a fluorinating agent, one F of N2F3 + was replaced by an azido group, but the substitution product was unstable and underwent rapid decomposition. The decomposition of complex fluoro salts of N2 + was studied both experimentally and computationally. It was shown that the life-time of FN5 is very short and that under our reaction conditions only the expected decomposition products can be observed. In pursuit of a bulk synthesis for N5- salts, it was shown that the N5- anion can be prepared in solution and be observed by 15N NMR. Reliable thermodynamic calculations were camed out for N5 +N5- and N5+N3-. It is shown that the previous use of vertical instead of adiabatic potentials led to very large errors and erroneuous conclusions.
