Zusammenfassung:	1387593 Dithiophosphoric acid esters HOECHST AG 22 March 1972 [23 March 1971] 13346/72 Headings C2P and C2C Compounds of Formula II where R and R1 are C 1-4 alkyl, R 1 is hydrogen of C 1-4 alkyl and R 2 is C 1-4 alkyl or C 2-7 alkoxyalkyl or R 1 and R 2 together with the N atom are alkylene-imino having 4 to 6 carbon atoms, one of which may be replaced by oxygen, are prepared by reacting a compound of Formula III with an alkali metal or ammonium salt of an O,O-dialkyldithiophosphoric acid to form an intermediate of Formula I and reacting this intermediate, with or without isolation, with an amine of formula The compounds of Formula I are claimed per se. The compounds of Formula II have pesticidal properties. The starting material, di-(4-chloroacetoxypheyl)-sulphone, is prepared by reacting di- (4-hydroxyphenyl)-sulphone with chloroacetyl chloride.
