Lactone Synthesis

Ruthenium-catalyzed formation of lactones from diols in aqueous medium has been demonstrated. 1,3,5-Triazaphosphaadamantane (PTA) included water-soluble ruthenium complexes [RuCl2(PPh3)(2,6-Py-(CH2-PTA)2]·2Br and [RuCl2(PPh3)2(2-PyCH2PTA)]·Br in the presence of KOH were found to be efficient for the synthesis of lactones from diols. The reported synthetic protocol is green as it uses water as solvent, avoids the use of any hydrogen acceptor/oxidant, and produces hydrogen as the only side product. Mechanistic studies revealed that lactone formation involved aldehyde intermediate and followed dehydrogenative pathway.

Retracted Article

Intercalation of montmorillonite by tetramethylammonium cations significantly increases the basal spacing, surface functionality, surface area, and thermal stability, leading to a significant enhancement in Cu(ii) Langmuir monolayer adsorption capacity (925.93 mg g−1).

The reaction has been studied spectrophotometrically; the reaction shows two steps, both of which are dependent on ligand concentration and show a limiting nature. An associative interchange mechanism is proposed. Kinetic and activation parameters ( and ) and (, , , and ) have been calculated. From the temperature dependence of the outer sphere association equilibrium constant, thermodynamic parameters ( and ; and ) have also been calculated.
