Full Title: Activation of the C{single bond}H bond in [(η5-C5H5)Fe(η5 -C5H4CH2N(CH3)CH2C 6H4R-4)] induced by platinum (II): Crystal structure of σ-Pt[(η5-C5H5) Fe(η5-C5H3CH2N(CH3) CH2C6H4OCH3-4)]Cl(DMSO). Condensations of ferrocenylcarboxaldehyde (1) and p-methyl (2b) or p-chlorobenzylamines (2d) in methanol resulted in ferrocenylaldimines 3b, d which were reduced by lithium aluminum hydride to give 4b, d, respectively. Reductive methylations of 4b, d with aqueous formaldehyde, sodium cyanoborohydride and acetic acid afforded the tertiary ferrocenylamines 5b, d. Treatment of 5a-e [(η5-C5H5)Fe(η5 -C5H4CH2N(CH3)CH2 C6H4R-4)] (R = CH3O(a), CH3(b), H(c), Cl(d), NO2(e)) with cis-[Pt(DMSO)2Cl2] in methanol produced predominately cycloplatinated complexes 6a-e σ-Pt[(η5-C5H5)Fe(η 5-C5H3CH2N(CH3) CH2C6H4-R-4)]Cl(DMSO) (R = same as before) in which the configurations consisted of RNRP and SNSP. In addition, the preferred activation of the C{single bond}H bond in the cyclopentadienyl ring rather than that in the phenyl ring was also observed. All compounds 3b-5b, 3d-5d, 6a-e were characterized by elemental analysis, IR and 1H NMR. The structure of 6a was determined by X-ray single crystal diffraction. The possible mechanism for the formation of 6 was discussed.
