遷移金属触媒を用いたジカルコゲニド結合の開裂を伴う有機モノカルコゲニド化合物の合成

抄録

A transition metal-catalyzed aryl carbon-chalcogen bond formation has been well performed by a combination of aryl halides and thiol or selenol under basic conditions. However, a catalytic process using dichalcogenides has been rarely explored to date . We have developed copper or nickel-catalyzed procedures, which realize preparation of unsymmetrical mono-chalcogenides from dichalcogenides with aryl halides under reductive conditions or with organoboronic acids under oxidative conditions. Furthermore, these reactions can utilize both organochalcogenide-groups on dichalcogenide.
