Preparation of 1-(benzenesulfonyl)-3-(2-triazinyl)ureas as plant growth regulators. Sorokin, V. I.; Kuznetsova, G. V.; Rusakova, N. I.; Tsybalova, L. A.; Melikhova, I. N.; Granina, T. E.; Drozd, V. N.; Shapovalov, A. A.; Loi, N. P.; et al. (All-Union Scientific-Research Institute of Chemicals for Plant Protection, USSR). PCT Int. Appl. WO 9113880 A1 19 Sep 1991, 56 pp. DESIGNATED STATES: W: AU, CH, DE, GB, JP, US. (World Intellectual Property Organization). CODEN: PIXXD2. CLASS: ICM: C07D251-52. ICS: A01N043-66; A01N043-70; A01N047-36. APPLICATION: WO 90-SU67 7 Mar 1990. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 5 The title compds. (I; R1 = Cl, NO2, CO2Me; R2 = H, Cl; R3 = H, Me; R4 = Me, Et, Ph, 2-ClC6H4) and salts with K, Na, and HOCH2CH2NEt2 were prepd., e. 64900-65-8 and 7019-16-1 are also in the experiment.g., by reaction of benzenesulfonyl isocyanates with 2-aminotriazines. Thus, 1 drop of Me2NCH2CH2NMe2 was added to a suspension of 0.0092 mol 2-amino-4-dimethylamino-6-(a-methyl)propylideneiminoxy-1,3,5-triazin e in 40 mL C6H6, the mixt. was heated to 50-60°, treated with 0.0092 mol 2-ClC6H4NCO, and the whole stirred for 2 h at 60° and 2 h at 20° to give 95% title compd. I (R1 = Cl, R2 = H, R3 = Me, R4 = Et) (II). The latter at 20 g/ha preemergence increased 130% mass of corn and 125% of cucumber plants, vs. 101 and 95%, resp., for gibberellin as a ref. I have little effect on weeds; e.g., II.Et2NCH2CH2OH under identical test conditions increased 105% the mass of Chenopodium album and had no effect on Setaria. Seventeen I were prepd. and converted to their Na, K, and HOCH2CH2NEt2 salts. .
