Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) [6] is an organic compound with the formula C 6 H 5 NH 2.Consisting of a phenyl group (−C 6 H 5) attached to an amino group (−NH 2), aniline is the simplest aromatic amine.
The hydrochloride salt of benzylamine, C 6 H 5 CH 2 NH 3 Cl or C 6 H 5 CH 2 NH 2 ·HCl, [24] is prepared by reacting benzylamine with hydrochloric acid, and can be used in treating motion sickness. NASA astronaut John Glenn was issued with benzylamine hydrochloride for this purpose for the Mercury-Atlas 6 mission. [25]
Cyclohexylamine is produced by two routes, the main one being the complete hydrogenation of aniline using some cobalt- or nickel-based catalysts: [4] C 6 H 5 NH 2 + 3 H 2 → C 6 H 11 NH 2. It is also prepared by alkylation of ammonia using cyclohexanol.
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 •.
Dibenzylamine is an organic compound with the formula (C 6 H 5 CH 2) 2 NH.It is classified as a secondary amine, being the middle member of the series that includes the primary amine benzylamine (C 6 H 5 CH 2 NH 2) and the tertiary amine tribenzylamine ((C 6 H 5 CH 2) 3 N).
Like other hydroxylamines it will react with aldehydes to form nitrones, illustrative is the condensation with benzaldehyde to form diphenylnitrone, a well-known 1,3-dipolar compound: [4] C 6 H 5 NHOH + C 6 H 5 CHO → C 6 H 5 N(O)=CHC 6 H 5 + H 2 O. Phenylhydroxylamine is attacked by NO + sources to give cupferron: [5] C 6 H 5 NHOH + C 4 H 9 ...
In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted ) is a quantitative measure of the strength of an acid in solution.
Dibenzylaniline or N,N-Dibenzylaniline is a chemical compound consisting of aniline with two benzyl groups as substituents on the nitrogen. The substance crystallizes in the monoclinic crystal system. The space group is P2 1 /n. The unit cell dimensions are a=11.751 Å b=9.060 Å c=29.522 Å, and β=94.589°.
