Detail of "18063-03-1"

Benzoylurea derivatives: Benzoylurea derivatives. Gamero Briones, Antonio (Union Explosivos Rio Tinto S. A. 35367-38-5 and 18063-03-1 are also occured in this study., Spain). Span. ES 534727 A1 1 Jan 1986, 9 pp. (Spain) CODEN: SPXXAD. CLASS: ICM: C07C127-19. ICS: C07C157-09. APPLICATION: ES 84-534727 30 Jul 1984. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Section cross-reference(s): 5 Benzoylurea derivs. I [X1, X2 = H, halo, Me, OMe; W1, W2 = O, S; R1 = H, alkyl, OH, alkoxy, alkoxymethyl, acyl, alkoxycarbonyl; R2 = H, cyclic or heterocyclic group, (un)substituted alkyl, aryl; R3 = (un)substituted Ph, pyridyl] are prepd. by condensation of benzamides II with carbamoyl halides ZC(:W2)NR2R3 (Z = halo) in a refluxing solvent. Thus, 2,6-F2C6H3CONH2 and ClCONHC6H4Cl-4 reacted over 4 h in refluxing PhCl to give 57% III, the insecticide diflubenzuron. .

Benzoylphenylurea derivatives: Benzoylphenylurea derivatives. Kishida, Hiroshi; Yano, Toshihiko (Sumitomo Chemical Co., Ltd., Japan). 15980-22-0 and 18063-03-1 are also occured in this study. Jpn. Kokai Tokkyo Koho JP 61207367 A2 13 Sep 1986 Showa, 7 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: C07C127-22. ICS: A01N047-34. APPLICATION: JP 85-49068 11 Mar 1985. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Section cross-reference(s): 5 The title compds. (I; R1 = H, halo; R2 = halo; R3 = halo, alkyl; R4 = 2,3,5- or 2,4,5-F3C6H2, FC6H4), useful as insecticides, were prepd. Thus, a mixt. of 4-amino-2,6-dimethylphenol and 2,3,5-F3C6H3 in Me2SO contg. CuCl and K2CO3 was refluxed for 6 h to give 4-(2,3,5-trifluorophenoxy)-3,5-dimethylaniline whose reaction with 2,6-F2C6H3CONCO in toluene at room temp. overnight gave I (R1 = R2 = F; R3 = Me; R4 = 2,3,5-F3C6H2). I at 3.5 ppm completely inhibited the emergence of Culex pipiens larvae. .
