Reaction of β-hydroxy or acetoxy sulfones with Sml2 in the presence of HMPA caused effectively reductive elimination to provide olefins. Treatment of enol phosphates, readily synthesized from β-hydroxy sulfones via keto sulfones, under the same conditions efficiently produced mono- and disubstituted acetylenes.
在HMPA存在下,β-羟基或乙酰氧基砜与Sml 2的反应引起有效的还原消除,从而提供了烯烃。在相同条件下处理由β-羟基砜通过酮砜轻松合成的烯醇磷酸酯,可以有效地生产单取代和二取代的乙炔。
