Di-omega-alkynyl aryl(arylalkyl) phosphonates
Abstract
Abstract INSECTIDICAL ESTERS OF CHRYSANTHEMUMIC ACID, E.G. PYRETHRINS, ALLETHRIN, ETC., FORM SYNERGISTIC INSECTICIDAL COMPOSITIONS IN COMBINATION WITH PHOSPHONATES HAVING THE FORMULA: ((Y)M-PHENYL)-(CH(-R))N-P(=X)(-O-R1-C*CH)-O-R2-C*CH WHEREIN R1 AND R2 ARE LOWER ALKYLENE GROUPS; R IS HYDROGEN, HALOGEN, A LOWER ALKYL OR ALKOXY GROUP, OR A SUBSTITUTED OR UNSUBSTITUTED PHENYL; N IS AN INTEGER FROM 0 TO 3, X IS OXYGEN OR SULFUR; AND Y REPRESENTS A VARIETY OF SUBSTITUENTS. THE PREPARATION AND PROPERTIES OF REPRESENTATIVE MEMBERS OF THIS NEW CLASS OF SYNERGISTIC PHOSPHONATES ARE DESCRIBED, AND TEST RESULTS OF THEIR SYNERGISTIC COMBINATIONS WITH REPRESENTATIVE CHRYSANTHEMUMATES ARE REPORTED.
