    摘要： PHOSPHORYLATED PHOSPHONIUM YLIDS REPRESENTED BY THE FORMULA

    R1-P(-R2)(-R3)=C(-R4)-P(=Y)(-Z1)-Z2

    WHEREIN EACH OF R1, R2 AND R3 ALKYL, CYCLOALKYL, ARYL, OR SUBSTITUTED ARYL; R4 IS HYDROGEN, ALKYL, CYCLOALKYL, ARYL OR SUBSTITUTED ARYL; Y IS OXYGEN OR SULFUR; AND EACH OF Z1 AND Z2 IS OR5 OR SR6 WHEREIN EACH OF R5 AND R6 IS ALKYL, ALKENYL, ARYL, OR SUBSTITUTED ARYL OR Z1 AND Z2 TOGETHER ARE

    -O-R9-O-, -O-R9-S-, -S-R9-S-

    WHEREIN R9 IS ALKYLENE OR ARYLENE. THE NOVEL YLIDS ARE USEFUL AS INTERMEDIATES IN THE PREPARATION OF PHOSPHONIC ACID OR THIOPHOSPHONIC ACID DERIVATIVES THEREFROM AND AS INTERMEDIATES FOR THE PREPARATION OF INSECTICIDES, HERBICIDES, OIL ADDITIVES AND 5'',6''-DIDEOXYHEXOFURANOSYLNUCLEOSIDE 6''-PHOSPHONIC ACID.
