Abstract

Nizom reakcija iz ferocena je pripravljen ferocenamin kao polazni spoj za daljnju oksidaciju
do nitrozoferocena pomoću komercijalnog reagensa Oxonea. Prilikom oksidacije
ferocenamina izoliran je nitroferocen te okarakteriziran difrakcijom rentgenskog zračenja na
jediničnom kristalu pri čemu je određena njegova kristalna struktura. U daljnjem istraživanju
provedena je sinteza i spektroskopska karakterizacija novih polimernih aromatskih azo
spojeva izravnom kondenzacijom na dva načina. Reakcijama odabranih aromatskih trinitro i
diamino, odnosno dinitro i triamino spojeva, u lužnatim uvjetima pripravljeni su azo produkti
okarakterizirani IR spektroskopijom, spektroskopijom NMR, rentgenskom difrakcijom na
praškastom uzorku, razlikovnom pretražnom kalorimetrijom i termogravimetrijom.
Usporedba difraktograma polikristalnih uzoraka te IR spektara polaznih spojeva i azo
produkata ukazuje na nastanak polimernih mrežastih struktura.

Abstract (english)

Ferroceneamine was synthesised in five subsequent reactions starting from ferrocene and was
used as the starting material for the synthesis of nitrosoferrocene by oxidation using
commercial oxidising agent Oxone. Nitroferrocene was isolated as product of the oxidation
and it's crystal structure was solved using single-crystal X-ray diffraction measurement.
Further, novel polymeric aromatic azo compounds were synthesized by direct condensation of
aromatic trinitro and triamino compounds with aromatic diamino and dinitro compounds,
respectively, in basic conditions. Prepared azo compounds were characterized using IR
spectroscopy, NMR spectroscopy, X-ray powder diffraction, differential scanning calorimetry
and thermogravimetry. Comparison of X-ray powder diffractograms and IR spectra of starting
materials and azo products indicated formation of polymeric azo compounds.
