General Description

4-tert-butylbenzenesulfonic acid is a chemical compound with the molecular formula C10H14O3S. It is a strong organic acid and a sulfonic acid derivative, with a bulky tert-butyl group attached to the benzene ring. 4-tert-butylbenzenesulfonic acid is commonly used as a catalyst in various chemical reactions, such as esterifications and Friedel-Crafts reactions, due to its ability to protonate a wide range of substrates. It is also utilized in the production of biologically active molecules, pharmaceuticals, and agrochemicals. Additionally, 4-tert-butylbenzenesulfonic acid has been shown to exhibit antimicrobial and antioxidant properties. However, it is important to handle this chemical with caution, as it is corrosive and may cause irritation to the skin, eyes, and respiratory system if not used properly.

Recognition of ionic guests by ionic β-cyclodextrin derivatives

Inclusion compounds of cationic, anionic, and neutral p-substituted derivatives of feri-butylbenzene complexed in β-cyclodextrin and its ionic 6-mono and 6-hepta derivatives were systematically investigated by isothermal titration calorimetry (ITC). All inclusion compounds showed 1:1 stoichiometry with binding constants ranging from 10 to 3 × 106 M -1. The binding free energies could be subdivided into apolar and electrostatic contributions. The electrostatic interactions could be quantitatively described by Coulomb's law by taking into account the degree of protonation of hosts and guests, the orientations of the guests within the hosts, and ion shielding as described by the Debye-Hueckel-Onsager theory. The orientations of the guests within the cyclodextrin cavities were determined by ROESY NMR spectroscopy.
