PREPARATION OF PHENYL TRIHALOVINYL SELENIDES AND SELENOXIDES
Martynov, A. V.,Mirskova, A. N.
, p. 2106 - 2108 (2007/10/02)
Phenyl trichlorovinyl selenide and phenyl 1,2-dichloro-2-bromovinyl selenide were obtained by the addition of phenylselenenyl chloride and bromide to dichloroacetylene with catalysis by Lewis acids.Hydrogen peroxide oxidation gave the corresponding selenoxides.
