General Description

White crystals or powder. Melting point 163-164°C. Readily soluble in organic solvents. Used for pre- and post-emergence weed control in cotton.

Reactivity Profile

Fluometuron is a trifluoromethyl urea derivative. May react with hypochlorites to form nitrogen trichloride which explodes spontaneously in air [J. Am. Chem. Soc. 63:3530-32]. May reacts with azo and diazo compounds to generate toxic gases. Reacts with strong reducing agents to form flammable gases.

Hazard

Toxic by ingestion. Questionable carcinogen.

Health Hazard

SYMPTOMS: Symptoms of exposure to Fluometuron may include possible convulsions or coma; irritation to the skin, gastrointestinal tract, respiratory tract; and lowered blood pressure.

Fire Hazard

Flash point data are not available for Fluometuron, but Fluometuron is probably combustible.

Flammability and Explosibility

Nonflammable

Agricultural Uses

Herbicide: A General Use Pesticide (GUP). Fluometuron is a selective herbicide which acts on susceptible plants by inhibiting photosynthesis. Fluometuron is registered by EPA exclusively for use on cotton and sugarcane. It can be applied pre-emergence, for weed control before planting, or post-emergence, after target crops and weeds come up, and may have residual activity for several months. Fluometuron is available in liquid, dry flowable, and wettable powder formulations.

Safety Profile

Moderately toxic by ingestion and intraperitoneal routes. Questionable carcinogen with experimental carcinogenic data. Mutation data reported. When heated to decomposition it emits very toxic fumes of Fand NOx

Potential Exposure

This material is used as a herbicide.

Environmental Fate

Soil. In soils, ?uometuron rapidly degrades (half-life approximately 30 days) to carbon dioxide, polar and nonextractable compounds (Hartley and Kidd, 1987; Humburg et al., 1989).Groundwater. According to the U.S. EPA (1986) ?uometuron has a high potential to leach to groundwaterPlant. In plants, ?uometuron degrades to a demethylated intermediate which subsequently is degraded to the aniline moiety (possibly m-tri?uoromethylaniline) (Hartley and Kidd, 1987; Humburg et al., 1989). Duke et al. (1991) reported that ?uometurChemical/Physical. Emits toxic fumes of nitrogen oxides and ?uorine when heated to decomposition (Sax and Lewis, 1987).

Preparation of N,N-Dimethyl-N′-arylureas using S,S-dimethyl dithio-carbonate as a carbonylating reagent

A new, general method for the preparation of N,N-di-methyl-N′- arylureas using S,S-dimethyl dithiocarbonate as a phosgene substitute is reported. The method has been set up according to four procedures, all including three steps: (1) reaction of S,S-di- methyl dithiocarbonate with dimethylamine to give S-methyl N,N-dimethylthiocarbamate; (2) halogenation with various halogenating reagents (chlorine, methanesulfenyl chloride, bromine, and meth-anesulfenyl bromide) to give N,N-dimethylcarbamoyl chloride or bromide; (3) in situ reaction with primary arylamines. All the target products were obtained in high yields (85-98%; 16 reactions, average yield 93%) and with high purity. Also noteworthy is the recovery of byproducts of industrial interest, namely methanethiol and dimethyl disulfide, with complete exploitation of the reagent S,S- dimethyl dithiocarbonate.

Synthesis of aromatic urea herbicides by the selenium-assisted carbonylation using carbon monoxide with sulfur

Commercially useful aromatic urea herbicides were synthesized in good yields from lithium amides of aromatic amines with thiocarbamates, which were prepared by the selenium-assisted carbonylation of secondary amines with carbon monoxide and sulfur under mild conditions.
