INVESTIGATION OF THE EXISTENCE OF OXYANIONS OF FLUORINE AND NITROGEN AND THE NITROGEN-FLUORINE CATIONS
Abstract
The preparation of trans-N2F2 from N2F4 and AlCl3 in a flow system is described. The thermal isomerization of trans-N2F2 to give cis-N2F2 must be conducted at low pressure to avoid decomposition. Both cis and transN2F2 are inert to water at ambient temperatures but hydrolyze slowly at 74-90C yielding mainly nitrogen, oxygen and hydrofluoric acid. The hydrolytic reactions of the N2F2 isomers are first order with respect to the nitrogen fluorides. Unlike NF3, cis and trans-N2F2 are not hydrolyzed via nucleophilic attack in aqueous solution as shown by the fact that caustic soda does not significantly accelerate the reactions. The mechanism of hydrolysis of cis and trans-N2F2 probably involves a bimolecular vapor phase decomposition reaction. No stable intermediates are formed in the hydrolysis reactions of cis or trans-N2F2.
