    Abstract: Bifunctional phenyl iso(thio)cyanate derivatives (I) are new. Also new are aniline and nitrobenzene derivative intermediates (II) and (V). Bifunctional phenyl iso(thio)cyanate derivatives of formula W=C=N-Ar-CO-NH-SO 2-A (I) are new. W : O or S; Ar : phenylene (optionally substituted by one or more of halo, 1-4C haloalkyl and CN), and A : NH 2 or the residue of a primary or secondary amine. Independent claims are also included for: (a) preparation of (I); (b) new aniline and nitrobenzene derivative intermediates of formulae H 2N-Ar-CO-NH-SO 2-A (II) and O 2N-Ar-CO-NH-SO 2-A (V), and (c) preparation of 4-(sulfamidocarbonyl-phenyl)-1,2,4-triazolinedione derivatives of formula (VI) by reacting an ester of diaza-ester of formula R 4>-NH-NR 3>-C(W')OR' (VII) and cyclizing the obtained urea derivative of formula R'O-C(=W')-N(R 3>)-N(R 4>)-C(=W)-NH-Ar-CO-NH-SO 2-A (VIII). [Image] W' : O or S; R 3>, R 4> : H, CN, NH 2, 1-6C alkyl, 1-6C haloalkyl, 1-6C alkoxy, 1-6C haloalkoxy, 3-7C cycloalkyl, 2-6C alkenyl, 2-6C haloalkenyl, 3-6C alkynyl, benzyl, OR 5> or (1-3C) cyanoalkyl, or R 3> + R 4> : a group completing 4-7 membered heterocyclyl optionally interrupted by S, O, NR 6> or N and optionally substituted by one or more of halo or 1-4C alkyl; R 5> : H, 1-6C alkyl, 1-6C haloalkyl, 3-7C cycloalkyl, 2-6C alkenyl, 3-6C alkynyl, optionally substituted phenyl or optionally substituted benzyl; R 6> : H, 1-6C alkyl, 3-6C alkenyl or 3-6C alkynyl, and R' : 1-4C alkyl. ACTIVITY : Herbicide. MECHANISM OF ACTION : None given.
