A novel, facile and efficient strategy for the one-pot synthesis of β-ketosulfones from readily available sulfonyl chloride, hydrazine hydrate and vinyl azides was described. The reaction proceeded very smoothly by affording diverse β-ketosulfones in moderate to good yields. This new procedure had the advantages of environmental benign, easy and simple operation, low cost and wide tolerance of functional groups, which provided a highly fascinating protocol to access β-ketosulfones. In the experiment, the researchers used many compounds, for example, Thiophene-2-sulfonyl chloride(cas: 16629-19-9Name: Thiophene-2-sulfonyl chloride)
Thiophene-2-sulfonyl chloride(cas: 16629-19-9) is a member of sulfonyl chlorides. Sulfonyl chlorides are reactive sulfonic acid derivatives similar in properties and reactivity to acid chlorides of carboxylates. The sulfonic acid group, however, is a highly hindered molecule, containing a tetrahedral configuration of substituents. Name: Thiophene-2-sulfonyl chloride
