Abstract:
Title compds. I (R= halo, C1-6 alkyl, C1-3 haloalkyl, C1-2 alkoxy, NO2; R1 = H, C1-6 alkyl; R2 = C1-6 alkylamino, C3-8 alkenylamino, C5-8 cycloalkylamino; X = O, S; n = 0-3 integer), useful as herbicides, insecticides, and nematocide, were prepd. by reaction of compds. II and phosphorous compds. III(one of A and B is halogen such as Cl, Br, the other SY(Y = H, metal cation). Thus, chloro acetanilide II (A = Cl) was mixed with ammonium salt (III; B = SNH4) of phosphorous compd. in glycoldimethylether for 3-5 hr at 50≦̸C to give I.
