The benzyl cation or phenylcarbenium ion is the carbocation with formula C 6 H 5 CH + 2; the benzyl anion or phenylmethanide ion is the carbanion with the formula C 6 H 5 CH − 2. None of these species can be formed in significant amounts in the solution phase under normal conditions, but they are useful referents for discussion of reaction ...
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.
The benzoyl functional group.. In organic chemistry, benzoyl (/ ˈ b ɛ n z oʊ ɪ l /, BENZ-oh-il) [1] is the functional group with the formula −COC 6 H 5 and structure −C(=O)−C 6 H 5. [2] [3] It can be viewed as benzaldehyde missing one hydrogen.
Indicative of its high reactivity (relative to alkyl chlorides), benzyl chloride slowly reacts with water in a hydrolysis reaction to form benzyl alcohol and hydrochloric acid. In contact with mucous membranes, hydrolysis produces hydrochloric acid. Thus, benzyl chloride is a lachrymator and has been used in chemical warfare. It is also very ...
Benzyl trichloroethanimidate. Carboximidates can act as protecting group for alcohols. [6] For example, the base catalyzed reaction of benzyl alcohol upon trichloroacetonitrile yields a trichloroacetimidate. This species has orthogonal stability to acetate and TBS protections and may be cleaved by acid hydrolysis. [7]
Over 2500 biologically active derivatives are known from the benzylisoquinoline alkaloids. [4] Based on their structure, the compounds can be divided into numerous subgroups: the aporphines, the phthalideisoquinoline alkaloids, the morphinans, the protoberberine alkaloids, and the pavins.
A classic organic reaction of benzil is the benzilic acid rearrangement, in which base catalyses the conversion of benzil to benzilic acid. This reactivity is exploited in the preparation of the drug phenytoin. Benzil also reacts with 1,3-diphenylacetone in an aldol condensation to give tetraphenylcyclopentadienone.
The symptoms caused by benzyl alcohol exposure include respiratory failure, hypotension, renal failure, severe metabolic acidosis, hematologic abnormalities, convulsions, paralysis gradual neurologic deterioration, cardiovascular collapse, sudden onset of gasping respiration, skin changes and vasodilation.
