Highly efficient stereoselective syntheses of novel bis( E -2-chlorovinyl) selenides and bis( E -2-bromovinyl) selenides in quantitative yields by reactions of selenium dichloride and dibromide with alkynes were developed. The reactions proceeded at room temperature as anti -addition giving products exclusively with ( E )-stereochemistry. The glutathione peroxidase-like activity of the obtained products was estimated and compounds with high activity were found. The influence of substituents in the products on their glutathione peroxidase-like activity was discussed.
