Abstract
Some new 5-benzylidene derivatives (II) have been synthesized by condensing I with benzaldehyde in the presence of anhydrous sodium acetate and several 5-p-dimethylaminobenzylidene derivatives. (III) have been synthesized by condensing I with p-dimethylaminobenzaldehyde in the presence of pyridine. Some selected arylidene derivatives have been tested for their nematicidal, insecticidal, acaricidal and herbicidal activities.
