Improved methods of synthesis are reported for FcCOC6H4F-4 1a, FcCOC6H4OMe-4 1b and Fcd(COC6H4OMe-4)2 2b [Fc = (C5H5)Fe(C5H4); Fcd = (C5H4)Fe(C5H4)]: demethylation of 1b and 2b, using AlCl3 in 1,1,2-trichloroethane, yields FcCOC6H4OH 1f and Fcd(COC6H4OH)2 2f respectively. Acylation of ferrocene using 4-phthalimidobenzoyl chloride yields 4-(phthalimidobenzoyl)ferrocene 1c, hydrazinolysis of which yields FcCOC6H4NH2-4 1d. Crystal structures are reported for 1d, 1f and 2f: in 1d and 1f the molecules are linked into spiral chains by means of N-H ... O=C and O-H ... O=C hydrogen bonds respectively; in 2f the O-H ... O=C hydrogen bonds link the centrosymmetric molecules into continuous two-dimensional nets, two independent sets of which are interwoven.
