Catching the couplings: A general and simple screening method for palladium‐catalyzed coupling reactions of aryl iodides utilizes gold nanoparticles. This assay was successfully employed in several aminations, α‐arylation of ketones, and decarboxylative couplings. 96 samples were screened in a few minutes.

A novel copper-catalyzed vinyl oxirane ring expansion protocol has been developed. A wide range of vinyl oxiranes can be rearranged to 2,5-dihydrofurans in excellent yields in the presence of electrophilic copper(II) acetylacetonate catalysts. Regioisomeric vinyl oxiranes can be converted to a single dihydrofuran product using these conditions. This method uses low catalyst loadings (0.5-5 mol %), has good tolerance of substitution patterns, and can be done in the absence of solvent.
