Preparation of pyridylphenoxyalkanoates as herbicides and plant defoliants and desiccants: Preparation of pyridylphenoxyalkanoates as herbicides and plant defoliants and desiccants. Schaefer, Peter; Hamprecht, Gerhard; Heistracher, Elisabeth; Menke, Olaf; Zagar, Cyrill; Rack, Michael; Goetz, Norbert; Harreus, Albrecht; Westphalen, Karl-Otto; Walter, Helmut; Mislitz, Ulf (BASF A.-G.In this study， 188025-19-6 and 7623-09-8 are also used., Germany). Ger. Offen. DE 19528943 A1 13 Feb 1997, 18 pp. (German). (Germany). CODEN: GWXXBX. CLASS: ICM: C07D213-61. ICS: C07D405-12; C07D409-12; A01N043-40; A01N043-34. ICA: C07D307-33. ICI: C07D405-12, C07D213-61; C07D305-10, C07D307-32, C07D309-20; C07D409-12, C07D213-61; C07D333-06, C07D335-02. APPLICATION: DE 1995-19528943 7 Aug 1995. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 5 Title compds. [I; R = Z1CR5R6COZ2R7; R1 = halo or haloalkyl; R2,R3 = H or halo; R4 = cyano or halo; R5,R6 = H or alkyl; R5R6 = (CH2)2-5; R7 = haloalkyl, alkenyl, alkynyl, etc.; R6R7 = alkylene; n = 0 or 1] were prepd. as herbicides and plant defoliants and desiccants (no data). Thus, I (R1 = CF3, R2 = R4 = Cl, R3 = F, n = 0)(II; R = OH) was etherified by ClCHMeCO2CH2CH:CH2 to give II (R = OCHMeCO2CH2CH:CH2). .

Carbostyril derivatives: Carbostyril derivatives. Nakagawa, Kazuyuki; Nishi, Takao; Oshiro, Yasuo (Otsuka Pharmaceutical Co., Ltd., Japan). Japan. Kokai JP 51118770 18 Oct 1976 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07D215-22. APPLICATION: JP 75-43610 9 Apr 1975.In this article, certain chemicals are used. Some of their cas registry numbers are 553-03-7 and 7623-09-8 DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) 6-(.alpha.-Haloalkanoyl)-3,4-dihydroxarbostyril derivs. I (R = alkyl, R1 = halo) were prepd. by treating 3,4-dihydrocarbostyril (II) with .alpha.-haloacyl halides, RCHXCOR2 (R2 = halo). Thus, 15 g II in CS2 was added to a mixt. of 80 g AlCl3 and 72 g MeCHClCOCl in refluxing CS2 to give 20 g I (R = Me, R1 = Cl). Analogously, I (R = Me, R1 = Br) and I (R = Et, R1 = Br) were prepd. .
