In IUPAC nomenclature, the prefix benzyl refers to a C 6 H 5 CH 2 substituent, for example benzyl chloride or benzyl benzoate. 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.

In organic chemistry, neighbouring group participation (NGP, also known as anchimeric assistance) has been defined by the International Union of Pure and Applied Chemistry (IUPAC) as the interaction of a reaction centre with a lone pair of electrons in an atom or the electrons present in a sigma or pi bond contained within the parent molecule but not conjugated with the reaction centre.
In relatively rare cases, Cp binds to metals via only one carbon center. These types of interactions are described as σ-complexes because they only have a σ bond between the metal and the cyclopentadienyl group. Typical examples of this type of complex are group 14 metal complexes such as CpSiMe 3. An example of both is (Cp 2 Fe(CO) 2).
Benzil (i.e. Bz 2, systematically known as 1,2-diphenylethane-1,2-dione) is the organic compound with the formula (C 6 H 5 CO) 2, generally abbreviated (PhCO) 2. This yellow solid is one of the most common diketones. Its main use is as a photoinitiator in polymer chemistry. [4]
Cr(η 6-C 6 H 6) 2, named as bis(η 6-benzene)chromium as all of the (contiguous) atoms in the benzene ligands are involved their position does not have to be specified [(1,2,5,6-η)-cycloocta-1,3,5,7-tetraene](η 5-cyclopentadienyl)cobalt in this only two (at positions 1 and 5) of the four double bonds are linked to the central atom.
Dimethylbenzylamine is the organic compound with the formula C 6 H 5 CH 2 N(CH 3) 2. The molecule consists of a benzyl group, C 6 H 5 CH 2, attached to a dimethylamino functional group. It is a colorless liquid. It is used as a catalyst for the formation of polyurethane foams and epoxy resins.
5 C 6 H 5 MgBr + 4 CrCl 3 → (C 6 H 5) 5 CrBr + 2 MgBr 2 + 3 MgCl 2 + 3 CrCl 2. This event marked an advance in organochromium chemistry at the time and "(C 6 H 5) 5 CrBr" was described to have salt-like properties. However, the reported workup procedures for "(C 6 H 5) 5 CrBr" was challenging and the yield was low.
