Palladium-catalyzed coupling reactions of 6,6′-dihydroxyboron-2, 2′-dimethoxy-1,1′-binaphthyl 5g and chloroarenetricarbonylchromium complexes 6a - c afforded complexes 7a - c with the binaphthyl residue directly linked to the (η6-arene)tricarbonylcriromium entity. Coupling reactions of 2,2′-dimethoxy, 3,3′diodo, and 6,6′-diodo-1, 1′-binaphthyl 3h and 5h with ethynylarenetricarbonylchromium derivatives 6d - f and ethynylferrocene 9 yielded binaphthyl compounds linked to arenetricarbonylchromium and feirocenyl derivatives 8a - c, 11a - c, 10, and 12 through a triple bond. Condensation of 2,2′-dimethylrriethoxy, 3-formyl, 1,1′-binaphthyl 2a with (η6-phenyl) methyltriphenylphosphonium tricarbonylchromium 13 and ferrocenylmethyltriphenylphosphonium 18 gave binaphthyl compounds linked to arenetricarbonylchromium and ferrocenyl derivatives 14 and 19, respectively, through a double bond. X-ray analyses of the dinuclear chromium complex 8a and of the mononuclear chromium complex 17-Z are described.
