Abstract
The synthesis and the chemical, physical and spectral properties of N-aminoglyphosate ethylester (hydrazino-N′-carbethoxymethyl-N′-methylphosphonic acid) 4a, H2OPCH2N(NH2)CH2CO2C2H5, of hydrazino-N′-carbethoxymethyl-N′-methyl-P-methylphosphinic acid 4b, CH3(HO2)PCH2N(NH2)-CH2CO2C2H5, and of azaglyphosate ethylester (hydrazino-N-carbethoxymethyl-N-methyl-phosphonic acid 9, H2O3PCH2NHNHCH2CO2C2H5, are described. 4a, 9 and 10 exhibit plant growth regulating properties.
