Benzyl group - Wikipedia
The term benzylic is used to describe the position of the first carbon bonded to a benzene or other aromatic ring. For example, (C6H5) (CH3)2C+ is referred to as a "benzylic" carbocation. The benzyl free radical has the formula C6H5CH2•.
Benzylic Bromination and Benzylic Oxidation - Master Organic …
Jun 13, 2018 · The carbon adjacent to an aromatic ring – the “benzylic” carbon – can participate in several useful and interesting reactions. Today we’ll provide examples and mechanisms for two key examples: benzylic bromination and benzylic oxidation. Here’s the quick summary: Table of Contents. Alkyl Groups = “Roughage”.
22.2: Benzylic Oxidations and Reductions - Chemistry LibreTexts
The benzylic hydrogens of alkyl substituents on a benzene ring are activated toward free radical attack, as noted earlier. Furthermore, S N 1 , S N 2 and E1 reactions ofbenzylic halides, show enhanced reactivity, due to the adjacent aromatic ring.

Reactions at the Benzylic Position - Chemistry Steps
The benzylic position is quite reactive and presents a useful synthetic tool for preparing many aromatic compounds. The reason for this reactivity is the resonance stabilization of the benzylic carbon regardless if the reaction goes through an ionic or radical mechanism. We will discuss each of these in the next sections.
16.4. The benzyl and related groups | Organic Chemistry II
16.4. The benzyl and related groups. This section gives some examples of benzylic groups, showing the resonance stabilization.
8.7: Benzylic Halides, Allylic Halides, Vinylic Halides, and Aryl ...
With the exception of iodine, these halogens have electronegativities significantly greater than carbon. Consequently, this functional group is polarized so that the carbon is electrophilic and the halogen is nucleophilic, as shown in the drawing below.
16.9: Oxidation of Aromatic Compounds - Chemistry LibreTexts
explain the stability of benzylic radicals in terms of resonance, and draw the resonance contributors of a given benzyl radical. explain, and illustrate with appropriate examples, the importance of benzylic bromides as intermediates in organic syntheses.
Feb 7, 2020 · Chapter 17 is all about reactions that happen at the position one away from an aromatic ring, or one away from a double bond. These are called the benzylic and allylic positions respectively. Benzyl and allyl are the names of the corresponding. R groups.
IUPAC - benzylic groups (B00632)
Feb 24, 2014 · The term 'benzylic position' or 'benzylic site' refers to the saturated carbon atom. A group, such as –OH, attached at a benzylic site is sometimes referred to as 'benzylic'. Source: PAC, 1995, 67, 1307.
