Abstract
The reaction of alkyl- and aryldichlorophosphines (or phosphonous acids) with N-benzylglycine and formaldehyde in acidic solution yields (N-benzyl-N-hydroxycarbonylmethyl-aminomethyl) alkyl- and -arylphosphinic acids in 50 to 100% yield. Debenzylation with hydrogen in the presence of Pd/C as a catalyst produces (N-hydroxycarbonylmethyl-aminomethyl) alkyl- and -arylphosphinic acids (R = H, R1 = alkyl, aryl). The preparation and properties of several salts and esters are also reported. The compounds possess contact herbicidal and plant growth regulating properties.Keywords
