Benzyl is not to be confused with phenyl with the formula C 6 H 5. The term benzylic is used to describe the position of the first carbon bonded to a benzene or other aromatic ring. For example, (C 6 H 5)(CH 3) 2 C + is referred to as a "benzylic" carbocation. The benzyl free radical has the formula C 6 H 5 CH 2 •.
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.
A carbocation is an ion with a positively charged carbon atom. ... bearing the general formula CR 5 + (R = alkyl or H). A typical example is the methanium ion, ...
The free benzyl anion has also been generated in the solution phase by pulse radiolysis of dibenzylmercury. [ 9 ] Early in 1904 [ 10 ] and 1917, [ 11 ] Schlenk prepared two red-colored salts, formulated as [NMe 4 ] + [CPh 3 ] − and [NMe 4 ] + [PhCH 2 ] − , respectively, by metathesis of the corresponding organosodium reagent with ...
A carbocation may be stabilized by resonance by a carbon–carbon double bond or by the lone pair of a heteroatom adjacent to the ionized carbon. The allyl cation CH 2 =CH−CH + 2 and benzyl cation C 6 H 5 −CH + 2 are more stable than most other carbenium ions due to donation of electron density from π systems to the cationic center. [20]
The following is a list of common functional groups. [3] In the formulas, the symbols R and R' usually denote an attached hydrogen, or a hydrocarbon side chain of any length, but may sometimes refer to any group of atoms.
In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a ...
The benzilic acid rearrangement is formally the 1,2-rearrangement of 1,2-diketones to form α-hydroxy–carboxylic acids using a base.This reaction receives its name from the reaction of benzil with potassium hydroxide to form benzilic acid.
