Synthesis, characterization, inequivalency of methylene proton and proton lability in the amino ligand of trans-[dichloro{(N-ferrocenyl methyl)amine}(η2-ethene)platinum] complexes
摘要:
A series of complexes of the type trans-W[PtCl2(eta(2)-ethene)(N-ferrocenyl methyl)amine)] complexes, N-ferrocenylmethylamine = [(eta(5)-C-5-H-5)Fe(eta(5)-C-5-H4CH2NHR], R = (Me, Pr-i, Bu-s, Bu-t, CH2Ph, (p-OCH3)Ph, (o-(OCH3)Ph, (p-CH3)Ph, (o-CH3)Ph, (m-CH3)Ph, (p-Cl)Ph) have been synthesized and characterized on the basis of elemental analysis, IR, H-1 and C-13 NMR spectroscopic methods. The CpCH2NHR (Cp = (eta(5) -C5H5)Fe(eta(5)-C5H4), region of the H-1 NMR spectrum of the complexes has been investigated and shown to contain inequivalent methylene protons, NH-CH and Pt-195 -N-CH coupling take place.

Hydroxy-, dimethylamino-, phenoxy-, and piperidino-groups have been displaced by anilinefrom the corresponding α-substitutedferrocenylmethanes. The anilino-group has been displaced from anilinomethylferrocene by p-methoxyaniline. The nucleophilic character of the attacking group has been shown to be important in this displacement.
Ferrocenylamines 2. Reductive methylation of secondary ferrocenylamines and ferrocenylaldimines: Synthesis, characterization of [(N-methyl-N-aryl)amino]methylferrocenes, 1-[(N-methyl-N-phenyl)amino]ethylferrocene and crystal structures of [(η5-C5H5)Fe(η5-C5H4CH2NHC6H4-Cl-4)] and [(η5-C5H5)Fe(η5-C5H4CH2N(CH3)-C6H4-OCH3-4)]
The reactions of ferrocenylaldimines (II) [(η5-C5H5)Fe(η5-C5H4CHNC6H4-R)] (R = 4-CH3O (a), 4-CH3 (b), H (c), 4-Cl (d), 3-Cl (e), 4-NO2 (f), 3-NO2 (g)) and ferrocenylketimine (I) [(η5-C5H5)Fe (η5-C5H4CH3CNC6H5)] with sodium borohydride in ethanol or lithiumaluminumhydride in THF resulted in secondary ferrocenylamines 3, 4. Reductive methylation of 3 (or II) and 4 with aqueous formaldehyde and sodium
