Mutagenicity of vinyl compounds in salmonella typhimurium

Teratogenesis, Carcinogenesis, and Mutagenesis, 1981
AbstractEighteen compounds structurally related to the mutagenic carcinogen vinyl chloride have been tested for mutagenicity in five strains of Salmonella typhimurium. Acrolein, acrolein diethylacetal, acrylonitrile, allyl alcohol, allyl bromide, crotonaldehyde, crotyl alcohol, and vinyl bromide were mutagenic with one or more strains; acrolein ...

Wool Modification by Activated Vinyl Compounds

Textile Research Journal, 1973
Wool has been modified with activated mono- and di-functional vinyl compounds in aqueous, dimethyl sulfoxide, and mixed media. Amino acid and chemical analyses showed that lysine and histidine wool side chains reacted in relative proportions dependent on the specific vinyl compound.

Intermolecular [5 + 1]-Cycloaddition between Vinyl Diazo Compounds and tert-Butyl Nitrite to 1,2,3-Triazine 1-Oxides and Their Further Transformation to Isoxazoles.

Organic Letters, 2021
1,2,3-Triazine 1-oxides are formed by nitrosyl addition from tert-butyl nitrite to the vinylogous position of vinyl diazo compounds. This transformation, which is a formal intermolecular [5 + 1] cycloaddition, occurs under mild conditions, with high ...

Brønsted Acid Catalyzed Oxocarbenium-Olefin Metathesis/Rearrangements of 1H-Isochromene Acetals with Vinyl Diazo Compounds.

Journal of the American Chemical Society, 2021
An oxocarbenium-olefin cross metathesis occurs during Brønsted acid catalyzed reactions of 1H-isochromene acetals with vinyl diazo compounds. Formally a carbonyl-alkene [2 + 2]-cyclization between isobenzopyrylium ions and the vinyl group of vinyl ...

Studies on diacetylenic vinyl compounds

Polymer Bulletin, 1989
The copolymerization of maleic anhydride(MAn) with phenyl-4'-vinylp henylbutadiyne(PVPB) was carried out using 2,2'-azobisisobu tyronitrile as an initiator. Although PVPB does not homopolymerize by free radicals in solution, it copolymerized giving copolymers having average molecular weights up to 12,000, and consisting of slightly more PVPB units. The

Nephrotoxicity of Halogenated Vinyl Cysteine Compounds

Journal of Urology, 1982
S-(1,2-dichlorovinyl) cysteine (DCVC), is a potent nephrotoxin. In order to determine if other vinyl cysteine conjugates were nephrotoxic, halogenated vinyl cysteines, HVC-1 and HVC-2, were prepared from chlorotrifluoroethylene (CTFE), a fluorocarbon monomer, or chlorotifluoroethylene, a metabolite of halothane, respectively. Three days after receiving

Sequential Cross-Coupling/Annulation of ortho-Vinyl Bromobenzenes with Aromatic Bromides for the Synthesis of Polycyclic Aromatic Compounds.

Angewandte Chemie, 2019
A sequential cross-coupling/annulation of ortho-vinyl bromobenzenes with aromatic bromides was realized, providing a direct and modular approach to access polycyclic aromatic compounds.

Reprocessing of Medical Vinyl Compounds

Journal of Vinyl and Additive Technology, 1996
Abstract There is increasing public concern over the disposal of plastic waste. The escalating cost of vinyl compounds would also make it desirable to reuse unavoidable process waste and surplus devices, not only in lower value markets, but also for medical device end users.

Studies on diacetylenic vinyl compounds

Polymer Bulletin, 1986
Synthese a partir de l'ethynyl-4 styrene et du phenyl bromoacetylene. Polymerisation lente avec l'AJBN en solution; a l'etat fondu, a 80°C, obtention d'un polymere insoluble. L'irradiation UV du cristal conduit a des polymeres solubles et insolubles. A −78°C, dans le THF, en presence de n-butyllithium, obtention de poly(p-phenylbutadiynyl styrene)

Topochemical polymerization of vinyl compounds

Radiation Physics and Chemistry (1977), 1980
Abstract The present situation of the solid state polymerization is subject to considerations according to those principles that were layed down by Prof. Michel Magat in his publication, entitled Polymerization in the Solid State ( Polymer , 1962, 3 , 449–463).
