Benzyl group and derivatives: Benzyl group, benzyl radical, benzyl amine, benzyl bromide, benzyl chloroformate, and benzyl methyl ether. R = heteroatom, alkyl, aryl, allyl etc. or other substituents. In organic chemistry, benzyl is the substituent or molecular fragment possessing the structure R−CH 2 −C 6 H 5.
For example, the amino acid tyrosine could be protected as a benzyl ester on the carboxyl group, a fluorenylmethylenoxy carbamate on the amine group, and a tert-butyl ether on the phenol group. The benzyl ester can be removed by hydrogenolysis, the fluorenylmethylenoxy group (Fmoc) by bases (such as piperidine), and the phenolic tert-butyl ...
Heavily studied examples are found in organolithium chemistry and organomagnesium chemistry. Some illustrative cases follow. Lithium-halogen exchange is essentially irrelevant to remediation, but the method is useful for fine chemical synthesis. [4] [5] [6] Sodium metal has been used for dehalogenation process.
Dimethylbenzylamine can then be converted into ammonia by performing demethylation twice, which removes both methyl groups, followed by debenzylation, removing the benzyl group using hydrogenation. [53] The diagram [which?] represents suggested pathways of the biodegradation of BAC for both the hydrophobic and the hydrophilic regions of the ...
Benzyl alcohol is used effectively for treating lice infestations as the active ingredient in lotion shampoo with 5% benzyl alcohol. [13] Benzyl alcohol is an ingredient used in the manufacture of soaps, topical creams, skin lotions, shampoos, and facial cleansers and is popular due to its anti-bacterial and anti-fungal properties.
Below is a schematic flow diagram of one method, involving extractive distillation, for extraction of the BTX aromatics from a catalytic reformate: [2] Schematic flow diagram for the extraction of BTX aromatics from a catalytic reformate.
Transesterification is the process of exchanging the organic functional group R″ of an ester with the organic group R' of an alcohol. These reactions are often catalyzed by the addition of an acid or base catalyst. [1] Strong acids catalyze the reaction by donating a proton to the carbonyl group, thus making it a more potent electrophile.
It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine. This essential amino acid is classified as neutral, and nonpolar because of the inert and hydrophobic nature of the benzyl side chain. The L-isomer is used to biochemically form proteins coded for by DNA.
