Zusammenfassung:1343204 Pesticidal thionophosphoric acid esters BADISCHE ANILIN- & SODAFABRIK AG 19 April 1971 [5 March 1970] 23058/71 Headings C2P and C2C Novel compounds of Formula I where R1 and R11 are C 1-4 alkyl and R111 is C 1-4 alkyl, aryl, substituted aryl, C 3-6 alkoxyalkyl or alkylthioalkyl, alkenyl, alkynyl, haloalkyl or cycloalkyl may be prepared by reacting a di- (C 1-4 alkyl) thionophosphorohalidate with a compound of Formula II or with a salt thereof. The sodium salts of the compounds of Formula II may be prepared by reacting a compound O = C = N-R111 with an N-hydroxy urethane to form a compound of formula and reacting this with sodium methoxide. The compounds of Formula I have insecticidal properties and may be used as the active ingredients in conventional pesticidal compositions.
