The kinetics and mechanism of decarboxylation of sodium perfluoro-2-methyl-3-oxahexanoate have been studied in aprotic (diethylene glycol dimethyl ether) and protic (ethylene glycol) solvents.In the synthesis of perfluoropropyl perfluorovinyl ether, the concurrent formation of 1,3,3,3-tetrafluoroethyl perfluoropropyl ether is thermodynamically more favorable.

Perfluoroalkylether amidoximes free from amide-contamination were prepared from imidate esters.The amidoximes were stable at 110 deg C; at ca. 170 deg C partial decomposition to 1,2,4-oxadiazoles, admixed with other compounds, took place.Interactions between nitriles and amidoximes at 50 deg C resulted in the formation of imidoylamidoximes; these dissociated readily into their constituents when subjected to higher temperatures.At 70 deg C and above, in the presence of excess nitrile or other ammonia acceptors, the imidoylamidoximes afforded high yields of the corresponding 1,2,4-oxadiazoles.

1,5-Bis(diphenylphospha)-3,7-bis(perfluoroalkylether)-2,4,6,8-tetraazacyclooctatetraene and 1,3-bis(diphenylphospha)-5,7-bis(perfluoroalkylether)-2,4,6,8-tetraazacyclooctatetraene were found to decompose at 316 deg C to phospha-s-triazines.The symmetrical arrangement liberated perfluoroalkylether nitrile with concommitant formation of the corresponding diphospha-s-triazine; the unsymmetrical isomer eliminated the (C6H5)2PN unit to give the monophospha-s-triazine.The thermal and oxidative stabilities of the two compounds differed widely with the unsymmetrical isomer being significantly more stable than the symmetrical arrangement.Spectral data pertinent to these results are discussed.Both materials were found to be effective in arresting perfluoroalkylether fluid degradation in oxidizing atmospheres in the presence of metal alloys.
