Bis(1,2-dionedioximato) complexes of Pt(ii) form linear chains of metal complexes that metallise under pressure. Through high-pressure structural, computational and conductivity measurements we show the crucial role of the ligand in dictating these properties.

Interchange Reactions

In this study, high pressure (HP)-induced denaturation of α-lactalbumin (α-la) and β-lactoglobulin (β-lg) in dairy systems was examined. In both milk and whey, β-lg was less baroresistant than α-la; both proteins were considerably more resistant to HP-induced denaturation in whey than in milk. HP-induced denaturation of α-la and β-lg increased with increasing proportion of milk in mixtures of milk and whey. Addition of a sulphydryl-oxidising agent, KIO3, to milk or whey increased HP-induced denaturation of β-lg, but reduced the denaturation of α-la. Denaturation of both α-la and β-lg was prevented by adding a sulphydryl-blocking agent, N-ethylmaleimide, to milk or whey prior to HP treatment, highlighting the crucial role of sulphydryl-disulphide interchange reactions in HP-induced denaturation of α-la and β-lg. Removal of colloidal calcium phosphate from milk also reduced HP-induced denaturation of α-la and β-lg significantly. The higher level of HP-induced denaturation of α-la and β-lg in milk than in whey may be the result of the abscence of the casein micelles and colloidal calcium phosphate from whey, which facilitate HP-induced denaturation of α-la and β-lg in milk.

Coupling of CO2 with epoxides is a green emerging alternative for the synthesis of cyclic organic carbonates (COC) and aliphatic polycarbonates (APC). The scope of this work is to provide a comprehensive overview of metal complexes having sulfur-containing ligands as homogeneous catalytic systems able to efficiently promote this transformation with a concise discussion of the most significant results. The crucial role of sulfur as the hemilabile ligand and its influence on the catalytic activity are highlighted as well.
