| 摘要 |
This invention relates to a new class of organic chemical compounds. More particularly, this invention is concerned with amido and hydrazido derivatives of N-phosphinothioylmethylglycine esters. This class of compounds has been found to be useful as herbicides. The compounds of the present invention are compounds of the formula. <CHEM> wherein R is a member of the group consisting of alkyl of from 1 to 8 carbon atoms, chloroalkyl of from 1 to 4 carbon atoms and from 1 to 3 chlorine atoms and alkoxyalkyl containing from 3 to 7 carbon atoms and wherein Z is a member of the class consisting of <CHEM> wherein each R min is individually selected from the class consisting of hydrogen, C1-C4 alkyl, C2-C4 alkenyl, C3-C7 cycloalkyl, benzyl or phenyl; a heterocyclic group selected from the class consisting of morpholine, pyrrolidine or piperidine; or a @-Z1 group wherein Z1 is a <CHEM> group wherein R sec is hydrogen, C1-C4 alkyl or phenyl; a heterocyclic group selected from the class consisting of piperidine, pyrrolidine and morpholine. |
