Cesium carbonate was used as a base to achieve the desulfurization reaction of alkenyl sulfonium salts and phosphine oxides at room temperature, forming C(sp2)—P bonds. This method features simple operation, mild reaction conditions, and good functional group compatibility, offering a straightforward and efficient preparation route for terminal vinyl phosphine oxides.

Key words: desulfonative coupling, vinyl phosphine oxide, C—P bond, alkenyl sulfonium salt
