Phenylsulfinylethylene

Synthesis and Photocatalytic Reactivity of Vinylsulfonium Ylides

“…Preparation of the lead compound 3a was envisaged through direct coupling of commercially available phenyl vinylsulfoxide 1 and the corresponding β-ketoester 2 by electrophilic activation (Scheme ). , Even though several side reactions could be anticipated, the desired vinylsulfonium ylide 3a was easily obtained when Tf 2 O was employed as activating agent, although in a modest 36% yield.…”
