ABSTRACT:
Substituted 5-benzylidenebarbituric acids have been prepared and characterized by 1H and 13C NMR spectral analysis. Investigation of substituents effect and mode of transmission of electronic effects have been carried out by 13C NMR chemical shifts measurement and correlated it with LFER parameters in substituted 5-benzylidenebarbituric acids.
KEYWORDS:
