Cyanide pentafluoride

Preparation. A compd C2F6N2 was reported in 1936 among the prods of the action of F on Ag cyanide (Ref 2), but the structure was not proved until 1940, when it was prepd in good yield by the action of 1 pentafluoride on I cyanide (Ref 4). Since then it has been prepd as the major prod from the action of Ag di-fluoride on cyanogen chloride (Refs 6 10) by the interaction of Cl, Na fluoride, and cyanogen chloride in a sealed tube at 50° for 1 hour (Refs 9 10) and in low yields by the fluori-nation of ethylene diamine or ethyleneimine (Ref 7)...

Tellurium chloride pentafluoride added under illumination to cyanogen chloride or to trifluoromethyl cyanide, formed an imino tellurium pentafluorides1 2 as colorless liquids. 

Chloro(trifluoromethyl)methyleneamino tellurium pentafluoride was similarly prepared2 from tellurium chloride pentafluoride and trifluoromethyl cyanide. The product could be purified only by preparative gas chromatography on a 15% Halocarbon K-352 column. The vapor pressure of the pure compound was 50 torr at 25°. 

SAFETY PROFILE Poison by subcutaneous, intravenous, and intramuscular routes. Moderately toxic by other routes. A severe eye irritant. Mutation data reported. Explosive reaction with potassium chlorate or bromine trifluoride. Violent reaction (ignition) with bromine pentafluoride, NH4, NO3, and IF7. Reaction with hydrogen cyanide may give the explosive nitrogen trichloride. When heated... 

AMMONIUM CHLORIDE (I2I25-02-9) Can be self-reactive explosion may occur when closed containers are opened after long storage. Contact with water can cause a violent reaction with heat and formation of hydrogen chloride. Violent reaction with boron trifluoride, boron pentafluoride, bromine trifluoride, iodine heptafluoride, potassium chlorate. Mixture with hydrogen cyanide may form explosive nitrogen trichloride. Incompatible with alkalis, alkali carbonates, acids, salts of lead or silver. At fire temperature conditions, fumes corrode metals.
