Nonclassical oxidation of cymenes

Journal of the Chemical Society D: Chemical Communications, 1971
Cobalt(III) ion-catalysed co-oxidation of p-cymene and butane affords predominantly p-isopropylbenzoic acid, contrary to the prediction based on the classical free-radical mechanism.

Health beneficial and pharmacological properties of p-cymene

Food and Chemical Toxicology, 2021
p-cymene also known as p-cymol or p-isopropyltoluene is an alkyl-substituted aromatic compound naturally occurring in essential oils (EOs) of various aromatic plants, including the genus of Artemisia, Protium, Origanum, and Thymus. It is related to the family of terpenes, especially monocyclic monoterpenes.

8-amino-p-cymene from p-cymene-trichloramine-aluminum chloride-t-butyl halide

Tetrahedron, 1967
Abstract p-Cymene was aminated on the isopropyl side-chain with trichloramine-aluminum chloride-t-butyl halide. At optimum conditions (p-cymene:trichloramine:aluminum chloride:t-butyl bromide = 1:0·1:0·2:0·3: 0–10°), 8-amino-p-cymene was obtained in 80% yield. Changes in temperature resulted in slightly lower yields.

[RuCl2(PH2Cy)(η6-p-cymene)]

Acta Crystallographica Section C Crystal Structure Communications, 1994
The structure of dichloro(cyclohexylphosphine)(η 6 -p-cymene)ruthenium, [RuCl 2 (η 6 -C 10 H 14 )(C 6 H 13 P)], is reported. The structure determination shows that the C atoms of the aromatic six-membered ring are almost equidistant from the Ru atom, at distances close to the average value of 2.21 (3) A. The other metal-ligand distances are Ru-P 2.299 (

Radical efficiency from azo-p-cymene

Tetrahedron, 1970
Abstract The first-order rate constants (ki) and efficiencies of radical formation (e) for azo-p-cymene were measured in ten solvents spanning 80-fold in absolute viscosity and 30-fold in dielectric constant. Although viscosity plays a major role in the cage effect, specific solvation of p-cymyl radicals must also be considered. The ki exhibit little

Hydrogen abstraction from the isomeric cymenes

Tetrahedron, 1989
Abstract The irradiation of cerium (IV) ammonium nitrate in the presence of ortho, meta and para cymene yields products from attack at the methyl group (the nitrates - these ones in 55 to 69% isolated yield-, the nitro derivatives, and the aldehydes) as well as at the isopropyl group (the acetophenones, not obtained from the ortho isomer), with ...
