Abstract
U ovom radu ispitana je kinetika i mehanizam reakcije PdCl2(DMF)2 s 4-dimetilaminoazobenzenom u N,N-dimetilformamidu. Mjerenja su izvršena pod uvjetima pseudo-prvog reda tj. u velikom molarnom suvišku PdCl2(DMF)2 u odnosu na 4-dimetilaminoazobenzen te pri različitim temperaturama. Rezultati kinetičkih istraživanja pokazali su da se u ovim eksperimentalnim uvjetima reakcije monopaladiranja, odnosno dipaladiranja, odvijaju u dva uzastopna koraka. U prvom brzom koraku dolazi do nastajanja mononuklearnog, LPdCl2(DMF), odnosno monociklopaladiranog adukta L[PdCl2(DMF)]2 nakon čega slijedi spori korak u kojem dolazi do pucanja orto C-H veze i nastajanja nove Pd-C veze. Aktivacijski parametri, ΔH, ΔS te ΔEa za oba reakcijska koraka su određeni i diskutirani.
Abstract (english)
In this work the kinetics and mechanism of reactions of PdCl2(DMF)2 with azobenzene and 4-dimethylaminoazobenzene in N,N-dimethylformamide were examined. The measurements were conducted under pseudo first order which means that one of the reactant was in molar excess, PdCl2(DMF)2. It was found that the mono- and dicyclopalladation reactions of azobenzenes proceed in two consecutive processes, adduct formation and palladation steps. The rate-determining step in both palladations is the breaking of the ortho C-H bond. From specific rate constants can be seen that the substitution of azobenzene significantly affect on the rate of complexation. From the resaults we see that by increasing the temperature we came to increase the constance rate.
