Palladium nanoparticles supported on Mg/Ca hydrotalcites catalyze the hydroarylation reaction of different alkynes and alkenes with aryl iodides under air in MeCN. The reaction of tertiary propargylic alcohols ( 1 ) with aryl iodides ( 2 ) yields, stereoselectively, γ,γ-diarylallylic alcohols ( 3 ) in moderate to high yields and high selectivity. Also, the HT/Pd hydroarylation reaction with aryl iodides was attempted on norbornene and α,β-unsaturated ketones affording, respectively, exo -aryl bicyclo[2.2.1]heptanes and β-aryl ketones in moderate to high yields. All the reactions described benefit from using a heterogeneous catalyst with evident advantages in terms of reaction purification and recyclability of the catalyst. Palladium nanoparticles supported on hydrotalcites catalyze the hydroarylation reaction of carbon-carbon multiple bonds.
