Abstract A series of 1-(substituted phenyl)-3-[α-(alkyloxyimino)-benzylidene]pyrrolidine-2,4-dione derivatives as a mixture of two geometrical isomers of Z-configuration and E-configuration were synthesized by the reaction of the corresponding α-hydroxybenzylidene analogs with alkyloxyamine hydrochlorides. The target compounds were confirmed by IR, 1H NMR, MS and elemental analysis. The title compounds
