Aminothiadiazoles and their use in combating unwanted plant growth

Aminothiadiazoles and their use in combating unwanted plant growth. Schirmer, Ulrich; Plath, Peter; Sauter, Hubert; Wuerzer, Bruno (BASF A.-G. , Fed. Rep. Ger.). Eur. Pat. Appl.In this article, certain chemicals are used. Some of their cas registry numbers are 87527-71-7 and 2270-20-4 EP 84673 A1 3 Aug 1983, 35 pp. DESIGNATED STATES: R: BE, DE, FR, GB, NL. (German). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: C07D285-12; A01N043-82; C07D417-04. APPLICATION: EP 82-111948 23 Dec 1982. PRIORITY: DE 82-3201861 22 Jan 1982; DE 82-3227554 23 Jul 1982. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 5 Herbicidal (no data) I [R = (un)substituted Ph; R1, R2 = H, cycloalkyl, Ph, (un)substituted alkyl; NR1R2 = heterocyclyl; Z = O, S; Z1 = alkylene; n = 0, 1] were prepd. Thus, 4-ClC6H4O(CH2)3CO2H was cyclocondensed with H2NNHC(S)NH2 to give I [R = 4-ClC6H4, R1 = R2 = H, Z = O, Z1 = (CH2)3, n = 1]. .
