Pentafluorotellurium hypohalites are reacted with fluorocarbon iodides to form intermediate adducts which are thereafter decomposed to form fluorocarbons containing the TeF.sub.5 O-- group.

Synthesis of R.sub.f OTeF.sub.5

A novel method for synthesizing pentafluorotellurium hypofluorite by effecting a reaction between B(OTeF.sub.5).sub.3 and elemental fluorine.

Process for preparing pentafluorotellurium hypofluorite

Multi-(OTeF.sub.5)-substituted fluorocarbons

A family of compounds using as energetic plasticizers having the general structural formula R--N(NO.sub.2)--CH.sub.2 CH.sub.2 CH.sub.2 (OCH.sub.2 CH.sub.2).sub.2 X wherein R is an alkyl group having from 1 to 10 carbon atoms and wherein X is a --ONO.sub.2 or --N.sub.3 radical, and their method of preparation.

Alkyl, azido, nitro ethers and method of preparation

Pentafluorotellurium hypofluorite and pentafluorotellurium hypochlorite have been reacted with olefinic reactants to form fluorocarbon adducts containing the oxypentafluorotellurium group (TeF.sub.5 O--).

Pentafluorotelluriumoxide fluorocarbons

A process for introducing a fluorine atom into an aromatic hydrocarbon by effecting a substitution reaction between an aromatic hydrocarbon and an NF.sub.4.sup.+ cation containing salt.

Method for introducing fluorine into an aromatic ring

The present invention concerns itself with a method for synthesizing hypofluorite compounds by utilizing fluorine fluorosulfate as a fluorinating agent and to a novel pentafluorotellurium hypofluorite compound prepared thereby.

Synthesis of pentafluorotellurium hypofluorite

A novel method is provided for the preparation of difluoramino trifluoromane by the direct fluorination of azidotrifluoromethane in the temperature range of 70.degree. C. to 80.degree. C. A potassium fluoride catalyst also may enhance the rate of reaction and increase the yield.

Novel method for the preparation of CF.sub.3 NF.sub.2

A method for synthesizing fluorocarbon halides by effecting a reaction at ambient temperatures between a fluorocarbon acid or its derivative and a halogen fluorosulfate.

Method for synthesizing fluorocarbon halides

A method for synthesizing perfluoroesters by effecting a reaction at subambient temperatures between a perfluorocarbon acid, or its derivatives, and a halogen fluorosulfate to produce an intermediate perfluoroacyl hypohalite which in turn is reacted with a suitable olefinic reactant to produce a perfluoroester.

Synthesis of fluorocarbon esters

A method of producing NF.sub.4 PF.sub.6 by a displacement reaction between NF.sub.4 BF.sub.4 and PF.sub.5.

Displacement reaction for producing NF.sub.4 PF.sub.6

Improved NF.sub.4.sup.+ compositions for solid propellant NF.sub.3 -F.sub.2 gas generators are described which produce NF.sub.3 and F.sub.2 free of gaseous Lewis acids and do not require clinker forming additives for their complexing. The novel self-clinkering compositions (NF.sub.4).sub.2 SnF.sub.6, NF.sub.4 SnF.sub.5, (NF.sub.4).sub.2 TiF.sub.6, NF.sub.4 Ti.sub.2 F.sub.9, NF.sub.4 Ti.sub.3 F.sub.13, and NF.sub.4 Ti.sub.6 F.sub.25 and processes for their production are disclosed.

Self-clinkering NF.sub.4 + compositions for NF.sub.3 -F.sub.2 gas

N.sub.2 F.sub.4 and SbF.sub.5 react in anhydrous HF to produce N.sub.2 F.sub.3 SbF.sub.6. The salt is useful as a burn rate modifier in NF.sub.3 -F.sub.2 gas generators.

N.sub.2 F.sub.3 SbF.sub.6 and its preparation

N.sub.2 F.sub.3 SnF.sub.5 is formed by reacting N.sub.2 F.sub.3 SbF.sub.6 and Cs.sub.2 SnF.sub.6 in the presence of HF. N.sub.2 F.sub.3 SnF.sub.5 is useful as a component of NF.sub.3 -F.sub.2 gas generating compositions.
