Abstract

[equation: see text] An efficient one-pot route to unsymmetrical diorganyl selenides has been developed by ruthenium(III) chloride catalyzed reactions of dibenzyl or diphenyl diselenides with alkyl halides in the presence of zinc. Organic iodides, bromides, and activated chlorides underwent the reactions efficiently. Unreactive organic chlorides also underwent the same type of selenation with sodium bromide as the additive.

摘要

[方程式：见正文] 通过氯化钌(III)催化二苄基二硒醚或二苯基二硒醚与卤代烃在锌存在下的反应，开发出了一种高效的一锅法合成不对称二有机硒醚的路线。有机碘化物、溴化物和活性氯化物能有效地进行该反应。不活泼的有机氯化物在添加溴化钠的情况下也能进行相同类型的硒化反应。
