A new catalytic protocol for the synthesis of selenoesters from aryl iodides and diaryl diselenides has been developed, where formic acid was employed as an efficient, low-cost, and safe substitute for toxic and gaseous CO. This protocol presents a high functional group tolerance, providing access to a large family of selenoesters in high yields (up to 97%) while operating under mild reaction conditions
已经开发了一种用于从芳基碘化物和二芳基二硒化物合成硒代酯的新催化方案,其中甲酸被用作有毒和气态 CO 的有效、低成本和安全的替代品。该协议具有高官能团耐受性,在温和的反应条件下以高产率(高达 97%)获得一大类硒代酯,避免使用难以操作、易氧化且气味难闻的硒醇。此外,通过首次使用二有机基二硫化物作为前体,该方法可以有效地扩展到具有中等至优异产率的硫酯的合成。
