order to elucidate the effect of a phenyl group at a remote position on the reactivity and the course of the reaction. The reactivities varied remarkably with the length of the alkyl chain(n); 2>>3 5>6. The rate enhancement was attributed to anchimeric assistance by a remote phenyl group, and the rate depression to the electron-withdrawing inductive effect of a phenyl group.

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).
