Article Synopsis
- A dinuclear molybdenum complex combined with urea hydrogen peroxide has been developed as an effective catalyst for converting thiols into uronium sulfonate salts with high yields (89-98%) in ethanol at room temperature.
- The reaction produced hydrogen gas, a pioneering finding in similar oxidation processes, and detailed product characterization was conducted using techniques like FTIR, NMR, and single crystal X-ray diffraction.
- Mechanistic studies revealed intermediate products including disulfides and sulfinic acids, while two specific reactions illustrated the conversion of uronium p-chlorobenzene sulfonate to sulfonic acid and diphenyl diselenide to selenonate salt.
Glycosylamine derivatives of 4,6-O-ethylidene-d-glucose have been used for complexing the alkali, alkaline earth and transition metal ions. Three different series of ligands have been reported where N-(o-carboxyphenyl)-4,6-O-ethylidene-β-d-glucopyranosylamine has been used for complexing the diamagnetic (Li, Na, K, Mg, Ca, Ba, Zn, Cd, Hg) metal ions. N-(2-Hydroxybenzoyl)-L-alanyl-4,6-O-ethylidene-β-d-glucopyranosylamine selectively interacts with molecular cupric acetate and the adduct acts as a catalyst in selective oxidation of primary and secondary alcohols into their corresponding carbonyl compounds.
