Synthesis of 3-Aryl-1H-Indazoles and Their Effects on Plant Growth

Indazoles are valuable because of their biological activities. A series of 3-aryl-1 H -indazoles have been synthesized by condensing bisulfite adduct of aromatic aldehydes with phenyl hydrazine in good yield. Different concentrations of indazoles were employed to check their effects on seed germinat...

Description
Summary:Indazoles are valuable because of their biological activities. A series of 3-aryl-1 H -indazoles have been synthesized by condensing bisulfite adduct of aromatic aldehydes with phenyl hydrazine in good yield. Different concentrations of indazoles were employed to check their effects on seed germination and early growth. The arylindazoles were proved to be growth inhibitors of root and shoot lengths of wheat and sorghum, especially at a high concentration (100 ppm). At lower concentrations growth inhibition was found to be less prominent. Seed germination and early growth of plantlets also depended on the nature of substitution on the aryl group.
