The thermal decarboxylation of alkali trichloroacetates in aprotic solvents. II. Decarboxylation in the presence of olefins

Autor: W. M. Wagner, S. van der Ven, H. Kloosterziel

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 80:740-746

The thermal decarboxylation of alkali trichloroacetates in aprotic solvents in the presence of olefins has been investigated. The isolation of dichlorocyclopropanes in good yields demonstrates the formation of CCl2 as an intermediate. By this method,

Some reactions of 1,1,1,3-tetrachlorobutane

Autor: E. C. Kooyman, W. M. Wagner

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 77:923-932

1,1,1,3-Tetrachlorobutane reacts with an excess of many nucleophilic reagents to give good yields of products Cl2C = CH-CHX-CH3, in which X may be an OH, O-alkyl, O-aryl, aryl-OH, NH2, alkylamino or dialkylamino group. Trichlorobutenes are probably i

Thermal decomposition of sodium trichloroacetate in 1,2-dimethoxyethane in the presence of various perchloro compounds leads to α,β-elimination of chlorine from these compounds and formation of CCl4. Hexachlorocyclopentadiene yields decachlorobi-(2

The thermal decarboxylation of alkali trichloroacetates in aprotic solvents IV decarboxylation in the presence of hexa- and pentachloroacetone

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 81:933-946

Thermal decarboxylation of sodium trichloroacetate in the presence of hexachloroacetone yields CO2, CO, CCl4, perchloroisopropenyl acetate and perchloroisopropenyl acrylate. A mechanism is suggested involving Cl+-abstraction by a CCl3− ion from the

The thermal decarboxylation of sodium trichloroacrylate in an aprotic medium

Autor: A. F. Bickel, H. Kloosterziel, W. M. Wagner, L. Vriesman

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 82:517-520

Sodium trichloroacrylate decomposes in 1,2-dimethoxyethane at 90° to give quantitative yields of CO2 and NaCl. Evidence is presented that this decarboxylation involves the trichlorovinyl anion, CCl2CCl−, as an intermediate.

Spinal spondylosis and acute intervertebral disc prolapse in a European brown bear (Ursus arctos arctos)

Autor: W M, Wagner, M P, Hartley, N M, Duncan, M G, Barrows

Publikováno v: Journal of the South African Veterinary Association. 76(2)

A 22-year-old male European brown bear (Ursus arctos arctos) was presented to the Onderstepoort Veterinary Academic Hospital after an acute onset of hind limb paralysis 4 days earlier. Previous radiographs revealed marked degenerative joint disease o

Publikováno v: Journal of the South African Veterinary Association. 76(1)

A 14-month-old female Eclectus parrot (Eclectus roratus) was presented with a 4-week history of bloody diarrhea and depression. No additional information could be gained from physical examination. Only selected diagnostic tests (faecal examination, h
