Zusammenfassung:Title compds. I(R = halo, C2-6 alkyl, C1-3 halogenoalkyl, NO2, C1-4 thioalkyl, OCH3; R1,R2,R3 = C1-6 alkyl; X = O, S; n = 1, 2, 3), useful as insecticides and nematocides, were prepd. by the reaction of compds, II and phosphorous compds. III(one of A and B is Cl or Br, the other SY; Y = H or metal cation). Thus, chloro acetylanilide II(A = Cl) and ammonium salt of phosphorous compds. III(B = SNH4) was stirred in glycolmethylether for 3-5 hr at 50 C to give I.
