    摘要: Phosphorus-containing compounds such as cyanophosphonate derivatives are important precursors for the synthesis of organophosphorus compounds, which have numerous applications, for example, in herbicides, insecticides, fertilizers, flame retardants and plasticizers. Cyanophosphonate derivatives can be further converted to aminomethylphosphonate derivatives, which have been particularly important precursors in the synthesis of N-phosphonomethyglycine, a highly effective commercial herbicide (available under the trade name Roundup) useful for the control of a large variety of weeds. The syntheses of such organophosphorus compounds have commonly used a hologen derivative of phosphorus as a starting material.

    摘要: A process for preparing a substituted polyazamacrocycle is provided which comprises contacting a diamine or triamine and a dicarboxylic acid or ester or anhydride thereof in the presence of a suitable base and a suitable solvent to produce the substituted polyazamacrocycle provided that when an ester of said dicarboxylic acid is used, said suitable base is optional, and when said dicarboxylic acid or an anhydride of said dicarboxylic acid is used, the reaction mixture further comprises a suitable coupling agent.
