(Matrix presented) We herein report that RuCl3/AgOTf has proven to be a hydroarylation catalyst with an efficiency and scope superior to previously known methods. This catalyst demonstrated consistent performance with arene-ene substrates of diverse structural features, providing good to excellent yields of cyclization products (chromanes, tetralins, terpenoids, dihydrocoumarins).

Te distribution of the deuterium in the benzocyclenes formed during the intermolecular cycloalkylation of 2-R-4-phenyl-2-butanol (R=CD3, CD2CH3, CH2CD3) in the presence of 85percent sulfuric acid was investigated by NMR spectroscopy and mass spectrometry.Hydrogen exchange takes place at the stage of formation of the γ-phenylalkyl cation, the average lifetime of which is sufficient for the establishment of an isotopic equilibrium by successive elimination addition of an deuteron.
