Reactions with Phosphorus and Arsenic Compounds

On heating phosphorus pentoxide and NF3 (1 1) in an autoclave to 480°C, POF3, NO, and NO2 are formed. With excess NF3 a small amount of NOPFe forms [1]  

Triphosphorus pentanitride, P3N5, reacts with NF3 to give the fluorocyclophosphazenes (NPp2)3 and (NPp2)4 in small amounts [2]. 

Ion cyclotron resonance spectroscopy has been used to observe fluorine atom and fluoride ion transfer from neutral NF3 to PFJ and PFJ, respectively, in PF3-NF3 mixtures according to the reactions PFJ + NF3- Pp4 + NF2 and PFJ + NF3 PF3 + Np2 [3]. Product distributions in the combustion system PF3-NF3-He calculated for various reactant ratios at 1500 and 2000 K are listed in [4]. 

No association between PF5 and NF3 was observed down to -128°C using infrared spectroscopy [5]. 

Phosphorus oxide fluoride, POF3, reacts with NF3 (1 1 ratio) in an autoclave at 480°C to yield 80% NOPFe and a small amount of PFg [6],
