Abstract

The ^13^C NMR spectra of twelve isomeric 2‐and 4‐(E)‐stilbenyloxyalkylthiouracils have been calculated and fully assigned. The A^i^ and A^i^K empirical parameters of 4‐ketopyrimidyl‐2‐thioalkoxy, 2‐ketopyrimidyl‐4‐thioalkoxy, 2‐(E) ‐stilbenyloxyalkyl, 2‐(E)‐stilbenyloxyalkylthio, 4‐(E)‐stilbenyloxyalkyl and 4‐(E)‐stilbenyloxyalkylthio groups were calculated for the predictions of the chemical shifts of substituted uracils and benzenes.
