SYNTHESIS OF FERROCENE METHYLAMINEPALLADACYCLES COMPOUNDS

ABSTRACT

1.The formyl ferrocene 1 was synthesizend by the condensation of the ferrocene and phosphorus oxychloride, N, N'-dimethylformamide, which reacted with hydroxylamine hydrochloride in the presence of sodium bicarbonate in methanol producing the formyl ferrocene oxime 2. The ferrocene oxime 2 was reduced by lithium aluminium hydride in dry tetrahydrofuran giving the ferrocene methylamine 3 , which were confirmed by infrared spectroscopy.
2.The four Schiff bases（4a、4b、4c、4d）  were synthesized by formyl ferrocene amine, Furfural, thiophene formaldehyde（benzaldehyde 、2,6 – Dichlorobenzaldehyde) in anhydrous methanol, respectively. Which were dealed with formaldehyde and reduced by sodium borohydride in methanol producing the ferrocenyl tertiary amine. The ferrocenyl tertiary amine were reacted with Li2PdCl4 in anhydrous methanol giving the dimer cyclopalladated compound, which were reacted with triphenylphosphine resulting in the monomer cyclopalaldated compound.
3. By infraring  redients spectroscopy and nuclear magnetic resonance to measured  the structure of compounds and by infraring cyclic voltammetry to measured  the performance  of  compounds .
