We employ the velocity map imaging technique to measure kinetic energy and angular distributions of state selected CH(3) (v(2)=0,1,2,3) and Br ((2)P(3/2), (2)P(1/2)) photofragments produced by methyl bromide photolysis at 215.9 nm. These results show unambiguously that the Br and Br( *) forming channels result in different vibrational excitations of the umbrella mode of the methyl fragment. Low...

in this research, an efficient synthesis toward 2-(2-((4-methoxybenzoyl)imino)-4-(4-methoxyphenyl)thiazol-3(2h)-yl)-2-phenylacetic acid via a three-component tandem reaction using aroylisothiocyanate, phenyl glycine, and 4-methoxyphenacyl bromide in an ionic liquid (il) has been described. 1-methyl-3-pentylimidazolium bromide (il) has been employed as a recyclable green solvent. the work-up pro...

There have been over 300 cases of methyl bromide poisoning reported in the literature. The first objective of this case report was to bring out an experience with the false belief that work in a closed space is safe when accompanied by the use of a cartridge respirator with activated charcoal. The second objective of this article was to demonstrate the marked toxicity of methyl bromide with the...

6-methyl- 1,2,4-triazine-3-(2h)-selenone-5(4h)-one(l) reacts in the presence of base with phenacyl bromide to give a mixture of compounds (2) and (3). this mixture is dehydrated in the presence of h,so, to give 3-phenyl-6 methyl-7h-selenazolo[3,2-b] [i ,2,4] triazin-7-one (6). for careful structure assignment of (6) its regioisomer 3-methyl-6-phenyl-4h-selenazolo [2,3-c] [ 1,2,4] triazin-4-one ...

Five dosages of methyl bromide were used to fumigate peanut (Arachis hypogaea L.) shells and whole pods of peanuts in 1-liter flasks for 24 hr at 25 C. Methyl bromide dosages as low as 24.5 mg/liter killed all Pratylenchus brachyurus (Godfrey) Filip. &Sch. Stech. in peanut shells. Dosages of 44.6 and 50.9 mg/liter killed all but one or two nematodes in shells of whole pods. A 15% reduction in s...

DESCRIPTION The active ingredient in ATROVENT (ipratropium bromide) Inhalation Aerosol is ipratropium bromide. It is an anticholinergic bronchodilator chemically described as 8azoniabicyclo[3.2.1]-octane, 3-(3-hydroxy-1-oxo-2-phenylpropoxy)-8-methyl-8-(1methylethyl)-, bromide, monohydrate (endo,syn)-,(±): a synthetic quaternary ammonium compound chemically related to atropine. The structural fo...
