Abstract

Abstract Diethylesters of 1-methyl-1-(N-substituted carbamoyl- or thiocarbamoyl-amino)-alkane-phosphonic acids are obtained by interaction of O,O-diethyl esters of 1-amino-1-methyl-alkanephosphonic acids and different isocyanates or isothiocyanates at room temperature. Cyclization of 1-methyl-I-(N-butylcarbamoyl-amino)-ethanephosphonic acid diethyl ester to 3-butyl-5,5,-dimethyl-2,4-dioxo-4-hydroxy-1,3,4-diazaphosphole is achieved.

STUDY ON THE KINETICS OF THE REACTION BETWEEN DIETHYL ESTER OF 1-AMINO-METHYL-ETHANEPHOSPHONIC ACID AND PHENYL ISOCYANATE

The reaction between diethyl ester of 1-amino-1-methyl-ethane phosphonic acid and phenylisocyanate is of second order, with the rate constant increasing at the advanced stage due to the autocatalytic effect of the reaction product.
