Methyl bromoacetate is an alkylating agent. It has been used to alkylate phenol and amino groups. [4] [5] Moreover, it can be used to make vitamins and pharmaceutical drugs. It is commonly used as a reagent in chemical modification of histidine. [2] In addition, methyl bromoacetate also use in synthesize of coumarins and cis-cyclopropane.
Bromoacetic acid is the chemical compound with the formula Br C H 2 CO 2 H.This colorless solid is a relatively strong alkylating agent.Bromoacetic acid and its esters are widely used building blocks in organic synthesis, for example, in pharmaceutical chemistry.
Benzyl bromide is an organic compound with the formula C 6 H 5 CH 2 Br. The molecule consists of a benzene ring substituted with a bromomethyl group. It is a colorless liquid with lachrymatory properties. The compound is a reagent for introducing benzyl groups. [3] [4]
It was used in World War I as a chemical weapon, called BA by British and B-Stoff by Germans. Due to its toxicity, it is not used as a riot control agent anymore. Bromoacetone is a versatile reagent in organic synthesis. It is, for example, the precursor to hydroxyacetone by reaction with aqueous sodium hydroxide. [6]
Mirzayanov gives little specific information about A-242, stating that it is highly toxic but no figures are given to compare it to other related agents. It is reportedly a solid rather than a volatile liquid as with most nerve agents, and in order to weaponise it successfully, it had to be milled into a fine powder form that could be dispersed ...
2-Phenylethyl bromide is an organobromide with the formula C 6 H 5 CH 2 CH 2 Br. It is a colorless liquid, although older samples appear yellow. Analogous to the preparation of most 1-bromoalkanes, it is prepared by free-radical addition of hydrogen bromide to styrene. These conditions lead to anti-Markovnikov addition, giving the 1-bromo ...
Xylyl bromide is an irritant and lachrymatory agent.It has been incorporated in chemical weapons since the early months of World War I.Some commentators say the first use was in August 1914, when the French attacked German soldiers with tear gas grenades, [2] [3] but the agent used in that incident was more likely to be ethyl bromoacetate, which the French had tested before the war.
Trimethylsilyl enol ethers react with NfF in the presence of a substoichiometric fluoride source at 0 °C to ambient temperature to give alkenyl nonaflates in moderate to good yields. Dried tetra-n-butylammonium fluoride was the preferred fluoride source in one study, [6] but CsF has been used in difficult cases with excellent results. [7]
