The order of directing ability is modified on complexation, the most remarkable change being the high efficiency of the F-group. The AB system of H-C(4) and H-C(5) of 4 overlaps with a signal associated with 3 (4.61 ppm). When the lithiation was carried out at -40°, 7 YO of 4 and 82 % of 3 were for
