Novel chlorinated phosphorylmethylcarbonyl derivatives of the formula <IMAGE> in which R1 represents an optionally substituted radical from the series comprising alkyl, aryl, aralkyl, alkoxy and aralkoxy and R2 represents an optionally substituted radical from the series comprising alkoxy and aralkoxy, or R1 and R2 together represent an alkanedioxy radical, X represents hydrogen or chlorine and R3 represents the grouping <IMAGE> in which R4 represents hydrogen or optionally substituted alkyl and R5 represents optionally substituted alkoxycarbonyl radical or an optionally substituted pyrazolyl radical; or if X represents chlorine, R3 also may represent optionally substituted radical from the series comprising alkyl, cycloalkyl, alkylamino and cycloalkylamino, which possesses fungicidal activity as well as herbicidal activity, but not against rice. Some intermediates are also new. |
