- REACTIONS OF CHALCOGENES WITH ACETYLENES. II. REACTION OF METALLIC SELENIUM WITH ACETYLENE IN HMPTA AND DMSO
-
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.

- ALKYL VINYL SELENIDES FROM ACETYLENE, ELEMENTAL SELENIUM, AND ALKYL HALIDES
-
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.
