Highly functionalized styrene derivatives have been synthesized in a single step by the palladium-catalyzed coupling of aryl bromides with tributylethenylstannane.Aryl bromides substituted with electron-withdrawing groups couple rapidly under the reaction conditions while bromides containing electron-donating substituents require further addition of catalyst for complete conversion. 1,4-Dibromobenzene can be coupled in a highly selective fashion with either 1 or 2 equiv of tin reagent to give 4-bromostyrene or diethenylbenzene, respectively.

Sulfenylation of β-diketones is challenging as β-diketones undergo deacylation after sulfenylation in the reaction medium. The sulfenylation of β-diketones without deacylation under metal-free conditions at ambient temperature via a cross dehydrogenative coupling (CDC) strategy is reported. The resultant products can be further manipulated to form α,α-disubstituted β-diketones and pyrazoles.
