15. Pyrolysis of Fluorinated Organic Compounds. I. The Pyrolysis of 1, 2-Dibromo-1-chloro-1, 2, 2-trifluoroethane and Some Related Halogenated Ethane Derivatives

Author

Park, J D, Lamb, R W, and Lacher, J R

Abstract

The synthesis of various halogenated ethane derivatives was performed by the pyrolysis of CF2Br-CFClBr and other similar compound. The reactions were carried out in a platinumlined tube at temperatures ranging from 350°C to 600°C alone and in the presence of nitric oxide or bromine. Various products were isolated and identified. A mechanism is postulated for the reaction.

16. THE SYNTHESIS OF SPECIAL FLUORINE-CONTAINING MONOMERS

Author

COLORADO UNIV AT BOULDER, Park, J D, Lacher, J R, COLORADO UNIV AT BOULDER, Park, J D, and Lacher, J R

Abstract

A large number of fluorine-containing intermediates were synthesized and submitted for further polymer studies. Among the organic fluorine compounds synthesized were (a) various bicyclobutenyl derivatives, (b) Grignard reaction products, (c) perhalocycloalkenes containing vinylic halogens (I, Br, Cl, F.) and (d) vinylic mono- and di-carboxylic acids of perhalocycloalkenes.

Abstract

A large number of fluorine containing intermediates were synthesized and shipped for further polymer studies. Among the organic fluorine compounds synthesized were: (a) various bicyclobutenyl derivatives (b) Grignard reaction products and pyrolysis materials obtained therefrom (c) unsaturated fluorine- containing halogenated (Br, Cl, I) cyclobutenes and (d) various alpha, omega- diolefins. Most of the above compounds were new to the arts.

18. THE SYNTHESIS OF SPECIAL FLUORINE-CONTAINING MONOMERS

Author

COLORADO UNIV AT BOULDER, Park, J. D., Lacher, J. R., COLORADO UNIV AT BOULDER, Park, J. D., and Lacher, J. R.

Abstract

Research on the synthesis of fluorine containing olefins and diolefins is reported. Dimerization reactions aimed at producing 'dibox' compounds are of particular interest. Reactions of note were those between 1,1, 2,2-tetrafluorobutadiene 1,3 and difluorodihaloethylene followed by dihydrohalogenation with alkali to yield 2,2'-dihalo-3,3',3',4,4,4'-octafluoro bicyclobutenes. Methods of dehydrohalogenations applied to these reactions makes available a number of dienes in good yield. Codimerization of these dienes is being continued.

Abstract

Olefins containing a vinylic chlorine as CF2=CFCl, CF2=CCl2, CFCl-CFCl were irradiated in the presence of NO to form nitroso compounds. The photochemical reaction of perfluoroolefins with NO were studied when NO2 was absent and then in the presence of chlorine. The study of the reaction of CF3COOH and C3F7COOH and their anhydrides with NO and NOCl.

Abstract

The synthesis of various halogenated ethane derivatives was performed by the pyrolysis of CF2Br-CFC1Br and other similar compounds. The reactions were carried out in a platinum-lined tube at temperatures ranging from 350 to 600 C alone and in the presence of nitric oxide or bromine. Various products were isolated and identified. A mechanism is postulated for the reaction. (Author), Reprint from Bulletin of the Chemical Society of Japan, 37:7, pp. 946-950, Jul 64. (Copies supplied by DDC)

24. NITROSO AND NITRO FLUOROHALOALKANES.

Author

COLORADO UNIV BOULDER, Park, J. D., Lacher,J. R., COLORADO UNIV BOULDER, Park, J. D., and Lacher,J. R.

Abstract

The report summarizes work in a program which was primarily concerned with the study of new approaches to the syntheses of of polyhalonitrosoalkanes and similarly related derivatives. Another objective was the study of various inorganic compounds as possible catalysts for the addition of NO, NO2 and NOCl across olefinic bonds. The kinetics of decarboxylation of some acyl nitrites were investigated. Vapor pressure measurements were also made in order to obtain the latent heats of vaporization as well as values for the Trouton's constant. (Author)
