  2. Benzyl chloroformate - Wikipedia

    en.wikipedia.org/wiki/Benzyl_chloroformate

    Benzyl chloroformate, also known as benzyl chlorocarbonate or Z-chloride, is the benzyl ester of chloroformic acid. It can be also described as the chloride of the benzyloxycarbonyl (Cbz or Z) group. In its pure form it is a water-sensitive oily colorless liquid, although impure samples usually appear yellow.

  3. Benzyl chloride - Wikipedia

    en.wikipedia.org/wiki/Benzyl_chloride

    Benzyl chloride reacts with aqueous sodium hydroxide to give dibenzyl ether. In organic synthesis, benzyl chloride is used to introduce the benzyl protecting group in reaction with alcohols, yielding the corresponding benzyl ether, carboxylic acids, and benzyl ester. Benzoic acid (C 6 H 5 COOH) can be prepared by oxidation of benzyl chloride in ...

  4. Williamson ether synthesis - Wikipedia

    en.wikipedia.org/wiki/Williamson_ether_synthesis

    The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol . This reaction was developed by Alexander Williamson in 1850. [ 2 ] Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an S N 2 reaction .

  5. Protecting group - Wikipedia

    en.wikipedia.org/wiki/Protecting_group

    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 ...

  6. Benzyl group - Wikipedia

    en.wikipedia.org/wiki/Benzyl_group

    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.

  7. Dibenzyl ether - Wikipedia

    en.wikipedia.org/wiki/Dibenzyl_ether

    It is classified as an ether derived from benzyl alcohol. A colorless, nearly odorless oil, the compound's main use is as a plasticizer . It is prepared by treating benzyl chloride with base.

  8. Peptide synthesis - Wikipedia

    en.wikipedia.org/wiki/Peptide_synthesis

    The (Z) group is another carbamate-type amine protecting group, discovered by Leonidas Zervas in the early 1930s and usually added via reaction with benzyl chloroformate. [34] Introduction of the Z protecting group from reaction with benzyl chloroformate (Z-chloride)

  9. Electrophilic aromatic directing groups - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_aromatic...

    An electron donating group (EDG) or electron releasing group (ERG, Z in structural formulas) is an atom or functional group that donates some of its electron density into a conjugated π system via resonance (mesomerism) or inductive effects (or induction)—called +M or +I effects, respectively—thus making the π system more nucleophilic.
