Amidothionophosphate nematocide

Amidothionophosphate nematocide. Kishino, Shigeo; Shimomatsu, Akio; Kume, Toyohiko (Nihon Tokushu Noyaku Seizo K. K., Japan). Japan. Kokai JP 52102429 27 Aug 1977 Showa, 11 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: A01N009-36. APPLICATION: JP 76-15833 18 Feb 1976. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemicals) Amidothionophosphates I (R1 = lower alkyl; R2 = lower alkyl, cycloalkyl, or phenylalkyl; X = H or halo; m = 1 or 2) are nematocides. Thus, 1.25 ppm O-Et O-2-cyanophenyl methylamidothionophosphate [41592-10-3] prepd. by esterification of O-Et methylamidochlorothionophosphate [682-90-6] with 2-cyanophenol [611-20-1] applied to soil killed nematodes in 4 wk.

Alkoxybenzonitriles

Alkoxybenzonitriles. (Kabushiki Kaisha Ueno Seiyaku Oyo Kenkyusho, Japan). Jpn. Kokai Tokkyo Koho JP 58152855 A2 10 Sep 1983 Showa, 2 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07C121-75; C07C120-00. APPLICATION: JP 82-35155 8 Mar 1982. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) 4-Methoxy- or 2-ethoxybenzonitrile was prepd. from the corresponding hydroxybenzonitriles by alkylation with Me2SO4 or Et2SO4 in aq. NaOH or K2CO3-xylene. Thus, 59.5 g 4-hydroxybenzonitrile and 20 g NaOH in H2O was treated dropwise with 75.6 g Me2SO4 at ￡10° and the mixt. heated 3 h to give 88.0% 4-methoxybenzonitrile.Except for chemicals metioned above, 767-00-0 and 611-20-1 are also used. .
