Steel carbonyl difluoride

Carbonylamino Tellurium Pentafluoride3 3.1 g (10 mmol) of trimethylsilylamino tellurium pentafluoride are placed in a 100 ml stainless steel cylinder which is then cooled. 1.98 g (30 mmol) of carbonyl difluoride are condensed into the cylinder which is then closed and heated at 60° for 15 h. The resultant mixture is distilled under a dynamic vacuum through —78° and —196° traps. The contents of the —196° trap are pumped... 

Small amounts of carbonyl difluoride are produced in the reaction of [Fe(CO)5] with tetrafluorohydrazine, NjF, in a steel bomb at about -10 C [594]. In contrast, NF3 and [Fe(CO)5] react only at temperatures above 100 C, and at 200 "C a vigorous combination takes place with the formation of FN=NF, CO, and iron fluorides. Only a small quantity of COF 3 is formed, probably from the reaction of CO with FeF3 [594].
