dc.description.abstract | Rate konstants for the reaction of eight 5-substituted orotic acids with diazodiphenylmethane (DDM) in dimethylformamide (DMF) were determined at 30 ºC by the known spectrophotometricmethod. The determined rate constants were correlated with the equations: logk2 = ασ1+βσR+h logk2 = ασ1+βσR+ψν+h to detect the presence and investigate the influence of both electrical and steric substituent effects. The obtained results show that the electrical effect (the localized – field and delocalized – resonance) is predominant and that the steric effect, althought present, is releatively small in this reaction. | en |
dc.description.abstract | Konstante brzine za reakciju osam 5-spstituisanih orotinskih kiselina sa diazodifenilmetanom (DDM) određene su na 30 ºC u dimetilformamidu (DMF) kao rastvarač u, poznatom spektrofotometrijskim metodom. Konstante brzina ispitivanih reakcija korelisane su sledećim jednačinama: logk2 = ασ1+βσR+h logk2 = ασ1+βσR+ψν+h sa ciljem da se odrede efekti supstituenata. Dobijeni rezultati ukazuju na to da su električni efekti supstituenata (induktivni i rezonantni) preovlađujući, a da su sterni efekti supstituenata, iako su prisutni, u odnosu na njih relativno mali. | sr |
