4-[(4-Methylbenzenesulfonamido)methyl]cyclohexanecarboxylic acid [PDF]

Acta Crystallographica Section E Structure Reports Online, 2011
The title compound, C(15)H(21)NO(4)S, crystallized with two independent mol­ecules in the asymmetric unit in which the dihedral angles between the mean planes of the benzene and cyclo­hexane rings are 78.3 (2) and 67.6 (2)°. The substituents of the cyclo­hexyl rings are in equatorial orientations.

Cyclohexanecarboxylic acid degradation with simultaneous nitrate removal by Marinobacter sp. SJ18

Environmental Science and Pollution Research, 2022
Abstract Naphthenic acid (NA), a new kind of toxic pollutants, is labeled as the potential threat to human health. However, the transformations of NAs in marine environments are still unclear. In this study, the characteristics and pathways of cyclohexylcarboxylic acid (CHCA) biodegradation were explored in the presence of nitrate.

Mechanistic Divergence in Sulfur‐Ligated Iron(III)‐Alkylperoxo Reactivity: Aldehyde Oxidation Prevails over Deformylation

Angewandte Chemie, Volume 137, Issue 43, October 20, 2025.
This study explores the mechanistic investigation into an unusual reactivity of a thioether‐ligated low‐spin Fe(III)‐alkylperoxide with cyclohexane–carboxaldehyde as a mimic of nonheme iron(II) enzyme intermediates and highlights that only efficient catalysis happens from a high‐valent iron(IV)‐oxo species.
