Oxalyl fluoride has been prepared directly in high yield from CO and the dioxygenyl salts O2[BF4] or O2[AsF6]. The formation of intermediate FCO radicals is indicated by differences in reaction rates and the observation of FC(O)OOC(O)F as a by-product. From the analysis of the NMR spectra of 13C enriched FC(O)C(O)F including selective irradiation experiments positive signs for both the FF (+50.6 Hz) and CC (+126.1 Hz) coupling constants are deduced. From the temperature dependency of 3J(FF), values of +70 Hz and -10 Hz are estimated for the trans- and cis-rotamers, respectively.
Kinetics of the thermal decomposition of bis(trifluoromethyl) peroxydicarbonate, CF3OC(O)OOC(O)OCF3

Thermal decomposition of bis(trifluoromethyl) peroxydicarbonate has been studied. The mechanism of decomposition is a simple bond fission, homogeneous first-order process when the reaction is carried out in the presence of inert gases such as N2 or CO. An activation energy of 28.5 kcal mol-1 was determined for the temperature range of 50-90°C. Decomposition is accelerated by nitric oxide because of a chemical attack on the peroxide forming substances different from those formed with N2 or CO. An interpretation on the influence of the substituents in different peroxides on the O-O bond is given.
