Thiohydroxamic esters derived from 5-(benzylseleon)pentanoic acid, 6-(benzylseleno)hexanoic acid and 7-(benzylseleno)heptanoic acid decompose smoothly upon irradiation, with the loss of carbon dioxide, to give tetrahydroselenophene, selenane and selenopane in good yield.

been prepared by the reaction of 1,4-dibromobutane or 1,5-dibromopentane with potassium chalcogenides. The novelty of the route consists of the use of the hydrazine hydrate–KOH system for the reductive generation of potassium selenide, telluride, diselenide or ditelluride from elemental chalcogens.
饱和杂环化合物C 4 H 8 Y,C 5 H 10 Y和C 5 H 10 Y 2(Y = Se或Te)是通过1,4-二溴丁烷或1,5-二溴戊烷与钾的反应制得的硫属化物。该路线的新颖之处在于使用水合肼-KOH系统还原性地从元素硫属元素生成硒化钾,碲化物,二硒化物或二碲化物。
