based on the reactions of selenium dihalides or monohalides with acetylene has been elaborated. Reactions of selenium tetrahalides with acetylene afford (E,E)-bis(2-halovinyl) selenides and (E)-2-halovinyl 1,2,2-trihaloethyl selenides. Convenient synthesis of (E,E)-bis(2-halovinyl) selenium dihalides in near quantitative yield has been developed. (E,E)-Bis(2-halovinyl) selenium dihalides undergo spontaneous
