By reactions of arenediazonium salts with trichloroethylene in aqueous acetone in the presence of alkali metal thiocyanates, bromides, or chlorides, catalyzed by Cu(II) or Fe(II) salts, we synthesized 1-thiocyanato(bromo, chloro)-1,2,2-trichloro-2-arylethanes.These were treated with alcoholic potassium hydroxide to give α,β,β-trichlorostyrenes.Trichloroethylene is less reactive in the anionarylation than vinylidene and vinyl chlorides.

Sodium dialkylphosphite reacts with trichlorovinylbenzene to yield in an one-batch procedure 1-phenyl-1,2,2-ethanetriphosphonic acid hexaalkyl esters.A carbanionic intermediate of an "anomalous Michaelis-Becker reaction" is deduced.Acidolysis of esters leads to the parent triphosphonic acids.NMR parameters of this acid are strongly influenced by protolytic equilibrium. - Key words: One-batch synthesis, Oligophosphonic Acid, NMR Spectra
CIDNP Studies of the Thermal Decomposition of Arylazo Aryl Sulfones

1H and 13C-CIDNP spectra were obtained during the thermal decomposition of several arylazo aryl sulfones (Ar-N=N-SO2-Ar') in tetrachloroethylene or 1,1,2,2-tetrachloroethane at 100 deg C.An enhanced absorption from the C1 of the starting material, azo sulfone, was observed; this indicates that the decomposition of azo sulfone proceeds by means of one-bond fission.The formation of sulfones (ArSO2Ar') and sulfinic esters (ArO(SO)Ar') as recombination products in a solvent cage was established from the signs of polarization (enhanced absorption or emission).
