Prenyl or dimethylallyl groups are common structural motifs in natural products and small molecule therapeutics. In this report, we describe a palladium-catalyzed method for the cross-coupling of aryl and heteroaryl boronic acids with prenyl alcohol. Catalyst systems based on dialkylbiaryl phosphines were highly active for this transformation. These supporting ligands provided opportunities for tuning the efficiency and regioselectivity of carbon–carbon bond formation. In addition, this method was further extended to the cross-coupling of symmetrical allylic alcohols with aryl boronic acids.

The di-?-methane rearrangement of a series of meta and para substituted arylvinylmethane reactants was investigated with the aim of determiningthe patterns of reactivity in systems in which initial excitation is localized in the aryl moiety.Thus the photo
