The biaryl coupling reaction of benzyl benzoate derivatives (3) and (4) was examined with copper(0) reagent. A dimerized product (9) was mainly obtained whereas the desired intramolecularly coupled product (11) was not detected when 3 was employed as the substrate. On the other hand, the reaction of 4 afforded a small amount of the desired lactone (14) although the main product was the dimerized 12.
