Abstract

1H-NMR spektroskopijom praćene su reakcije nastajanja ciklopaladiranih azobenzena u N,N-dimetilformamidu, a kao prekursor je korišten paladijev(II) acetat. Mjerenja su izvršena uz trostruki molarni suvišak Pd(OAc)2.
Rezultati su pokazali da u reakciji 4-dimetilaminoazobenzena i Pd(OAc)2 nastaju i monopaladirani i dipaladirani kompleks dok u reakciji 4-dimetilamino-4'-nitroazobenzena i Pd(OAc)2 unutar 72 sata i pod ovim reakcijskim uvjetima nastaje samo monopaladirani kompleks. Iz ovisnosti... More promjene koncentracije monopaladiranih kompleksa o vremenu izračunane su konstante brzine reakcija. Less

Abstract (english)

In this work the formation of cyclopalladated azobenzenes were monitored by 1H-NMR spectroscopy. The solvent was N,N-dimethylformamide and as a Pd precursor palladium(II) acetate was used. The measurements were carried out with three-fold molar excess of Pd(OAc)2. The results have shown that in the reaction of 4-dimethylaminoazobenzene and Pd(OAc)2, dicyclopalladated and monocyclopalladated complex are formed. On the other hand, the reaction of 4-dimethylamino-4'-nitroazobenzene with... More Pd(OAc)2 during 72 hours leads only to monocyclopalladated complex. Less
