The effect of the conditions in the reaction of selenium with acetylene (the concentration and nature of the alkali-metal hydroxide, the temperature, the concentration of water, the addition of stannous chloride) on the yields of divinyl selenide, 2-vinyloxy-1,3-butadiene, and selenophene was investigated.It was shown that the formation of divinyl selenide under the reaction conditions is accompanied by its transformation into selenophene.

In the reaction of elemental selenium with acetylene at 90-115 deg C in an aqueous alkaline medium or in the HMPTA-potassium hydroxide-water and DMSO-potassium hydroxide-water systems the main direction of the reaction, leading to divinyl selenide, is accompanied by side processes leading to the formation of vinyl ethyl selenide, 1,3-di(vinylseleno)butane, 2,5-dimethyl-4-methylene-1,3-oxaselenolane, 2-vinylseleno-1-buten-3-ol, cis-1-vinylseleno-1-buten-3-ol, cis,cis-di(3-hydroxy-1-butenyl)selenide, and also selenophene and 2-vinyloxy-1,3-butadiene.

Elemental selenium reacts with acetylene and alkyl halides when heated (105-115 deg C) in an aqueous alkaline medium and gives alkyl vinyl selenides (with yields of up to 44percent) in addition to divinyl and dialkyl selenides.
