ADVANCED OXIDIZER RESEARCH
Abstract
Synthetic routes to cyclohexyldifluoramine were investigated. Fluorination of ethyl N-cyclohexylcarbamate was the most efficient of the procedures attempted. Cyclohexylidenefluorimine was prepared by the dehydrofluorination of cyclohexyldifluoramine. The addition of N2F4 to 2- pentene produced 2,3-bis-(NF2) pentane in its two diastereoisomeric forms. 2,2- Bis(NF2)phenylethane was synthesized. The stoichiometry of the adduct of N2F4 with AsF5 at room temperature was confirmed to be 1:1. The uptake of AsF5 by N2F4 at -80 C produced adducts in which the AsF5:N2F4 ratios were 2 or greater. The F19 n.m.r. spectrum of HF solutions of the 1:1 adduct indicates the presence of 3 nonequivalent N-F fluorines, interpreted as evidence of the existence of an N2F3(+) cation. Attempts to prepare O2BrF5 are reported. A method for preparation of high-purity NH3OHClO4 in reasonably short time was developed; thermal decomposition studies are discussed.
