In the presence of NaH and DMF, Isatoic anhydride was alkylated with alkyl halide such as iodomethane, iodoethane, iodoprpopane, 2-methoxy ethyl chloride to afford N-alkyl isatoic anhydride analogues.
Methyl iodide (CH3I, iodomethane, MeI) is a commercially available alternative to MeBr for fumigation (Ohr, Sims, Grech, Becker, & McGiffen, 1998) and is a registered pesticide in several countries around the world with fungicide, herbicide, insecticide, nematicide, and soil disinfectant properties similar to those of MeBr.
Iodomethane, anhydrous DMSO, 2,5-dihydroxybenzoic acid (DHB), sodium hydroxide, trifluoroacetic acid (TFA), and sodium acetate were purchased from Sigma-Aldrich.
The treatments-1,3-dichforopropene + chloropicrin (578 kg/ha shank injected), iodomethane + chloropicrin (515 kg/ha shank injected or 448 kg/ha drip applied) and propargyl bromide (221 kg/ha shank injected or 207 kg/ha drip applied)--controlled root-knot and citrus nematodes equal to methyl bromide (507 kg/ha shank injected) during an eight-year evaluation period.
Four more peaks are clearly identified, in ascending order: acetone, iodomethane, benzene, and tert-butylbenzene.
In an effort to avoid jumping from the frying pan into the fire, the EPA is conducting a soil fumigant cluster risk assessment for methyl bromide, chloropicrin, 1,3-D, metam sodium, dazomet, and iodomethane.
Results from tests they conducted in 2000 suggest that propargyl bromide or another contender, iodomethane, does as good a job--or nearly so--as methyl bromide plus chloropicrin in quelling some of a flower's worst soil-dwelling enemies.
Early tests indicate that iodomethane is extremely effective against a broad spectrum of fungi, weeds and nematodes, giving it an edge over other proposed substitutes that control only one or two types of soil-borne pests.
Health and Safety Executive carries out numerous CBAs of controls on various substances, mainly relating to occupation exposure, including propylene oxide, PCB s, platinum soluble salts, o-toluidine, iodomethane, cotton dust, softwood dust, azodicarbonamide, antimony, triglycidylisocyanurate (TGIC), and wool process dust.
The reagents used in this study are as follows: 4-4'-oxydianiline (ODA; 97% purity), 4,4'-methylenebis (phenyl isocyanate) (MDI; 98% purity), N-methyl pyrolidinone (99% purity), and iodomethane were purchased from Sigma--Aldrich Company.
We purchased the matrix, 2,5-dihydroxybenzoic acid (DHB), trifluoroethanol, sodium hydroxide, CHAPS, Tris-HCl, sodium pyrophosphate, EDTA, and EGTA from Aldrich; chloroform, iodomethane, and sodium chloride from EM Science; dithiothreitol (DTT) and iodoacetamide (IAA) from Bio-Rad Laboratories; ammonium bicarbonate from Mallinckrodt Chemical Company; and acetonitrile from Fisher Scientific.
TOKYO -- Arysta LifeScience is pleased to announce YOKAFUME([R]),()a broad-spectrum soil fumigant containing iodomethane (methyl iodide), is now available for commercial use in Japan.
