Abstract: A set of 22 anilinomethylidene derivatives (13 new ones) of di(m)ethyl malonate, malonodinitrile and pentane-2,4-dione with various substituents in position 4- and 3-, respectively were prepared to study the characteristic influence of these substituents and solvents on chemical shifts in 13C NMR spectra and like reference compounds for kinetic measurements.

Keywords: NMR spectroscopy, substituent chemical shifts (SCS), arylaminomethylidene derivatives, enamines
