General Description

1,1,1,2,2,3,4,5,5,6,6,6-dodecafluoro-3,4-bis(trifluoromethyl)hexane is a chemical compound with the molecular formula C8F12, and it belongs to the group of fluorocarbons. It is a colorless, odorless, and non-flammable liquid with a high boiling point and low viscosity. 1,1,1,2,2,3,4,5,5,6,6,6-dodecafluoro-3,4-bis(trifluoromethyl)hexane is primarily used as a refrigerant and a blowing agent for foam insulation. It is also utilized in the production of aerosol propellants, solvents, and cleaning agents. Due to its stable chemical structure and non-toxic properties, it is considered to be an environmentally friendly alternative to other industrial chemicals. However, it is important to handle and dispose of this compound carefully to prevent any potential negative impacts on the environment.

REACTIONS OF TETRAFLUOROETHYLENE OLIGOMERS. PART 1. SOME PYROLYTIC REACTIONS OF THE PENTAMER AND HEXAMER AND OF THE FLUORINE ADDUCTS OF THE TETRAMER AND PENTAMER

Pyrolyses of these highly branched fluorocarbons over glass beads caused the preferential thermolyses of C-C bonds where there is maximum carbon substitution.Fluorinations of perfluoro-3,4-dimethylhex-3-ene (tetramer) (I) and perfluoro-4-ethyl-3,4-dimethylhex-2-ene (pentamer) (II) over cobalt (III) fluoride at 230 deg C and 145 deg C respectively afforded the corresponding saturated fluorocarbons (III) and (IV), though II gave principally the saturated tetramer (III) at 250 deg C.Pyrolysis of III alone at 500-520 deg C gave perfluoro-2-methylbutane (V), whilst pyrolysis of III in the presence of bromine or toluene afforded 2-bromononafluoorobutane (VI) and 2H-nonafluorobutane (VII) respectively.Pyrolysis of perfluoro-3-ethyl-3,4-dimethylhexane (IV) alone gave a mixture of perfluoro-2-methylbutane (V), perfluoro-2-methylbut-1-ene (VIII), perfluoro-3-methylpentane (IX), perfluoro-3,3-dimethylpentane (X), and perfluoro-3,4-dimethylhexane (III).Pyrolysis of IV in the presence of bromine gave (VI) and 3-bromo-3-trifluoromethyldecafluoropentane (XI): with toluene, pyrolysis gave VII and 3H-3-trifluoromethyldecafluoropentane (XII).Pyrolysis of II at 500 deg C over glass gave perfluoro-1,2,3-trimethylcyclobutane (XIII) and perfluoro-2,3-dimethylpenta-1,3(E)- and (Z)-diene (XIV) and (XV) respectively.The diene mixture (XIV and XV) was fluorinated with CoF3 to give perfluoro-2,3-dimethylpentane (XVI) and was cyclised thermally to give the cyclobutene (XIII).Pyrolysis of perfluoro-2-(1'-ethyl-1'-methylpropyl)-3-methylpent-1-ene (XVII) (TFE hexamer major isomer) at 500 deg C gave perfluoro-1-methyl-2-(1'-methylpropyl)cyclobut-1-ene (XVIII) and perfluoro-2-methyl-3-(1'-methylpropyl)buta-1,3-diene (XIX).Fluorination of XVIII over CoF3 gave perfluoro -1-methyl-2-(1'-methylpropyl)cyclobutane (XX), which on co-pyrolysis with bromine gave VI.XIX on heating gave XVIII.Reaction of XVIII with ammonia in ether gave a mixture of E and Z 1-trifluoromethyl-2-(1'-trifluoromethylpentafluoropropyliden-1'-yl)tetrafluorocyclobutylamine (XXI) which on diazotisation and hydrolysis afforded 2-(2'trifluoromethyltetrafluorocyclobut-1-en-1'-yl)-octafluorobutan-2-ol (XXII).
