Photochemical behavior of chlorsulfuron in water and in adsorbed phase

Photochemical behavior of chlorsulfuron in water and in adsorbed phase. Herrmann, M.; Kotzias, D.; Korte, F. (Inst. Oekol. Chem., Ges. Strahlen- Umweltforsch. m.b.H. Muenchen, Freising-Attaching D-8050, Fed. Rep. Ger.). Chemosphere, 14(1), 3-8 (English) 1985. CODEN: CMSHAF. ISSN: 0045-6535. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) The photochem. of the herbicide chlorsulfuron [64902-72-3] was investigated in MeOH [67-56-1], distd. water, natural creek-water, on silica gel and on montmorillonite [1318-93-0] surfaces. The rate of degrdn. was detd. in outdoor and indoor expts. simulating tropospheric conditions (l > 290 nm). Two major photoproducts, i.e., 2-chlorobenzene sulfonamide [6961-82-6] and 2-methoxy-4-methyl-6-amino-1,3,5-triazine [1668-54-8], were identified in all cases.

DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 5 Fungicidal and plant growth regulating (no data) I [R = (un)substituted Ph, furyl, thienyl, pyrrolyl, pyridinyl; R1 = alkyl, alkoxy, haloalkoxy; R2 = alkylthio, halo, amino, R1; X = N, CH] were prepd. Thus, H2NCO2Et was acylated with 2-(F2CHO)C6H4SO2Cl to give 23.3% 2-(F2CHO)C6H4SO2NHCO2Et. This was treated with 2-amino-4-methoxy-6-methyl-1,3,5-triazine to give 23.In this experiment, several chemicals are used like 1668-54-8 and 67359-63-1 1% I [R = 2-(F2CHO)C6H4, R1 = MeO, R2 = Me, X = N]. Fifteen other carbamate intermediates were prepd. .
