Baeyer-Villiger monooxygenases (BVMOs) can catalyze the asymmetric sulfoxidation to form pharmaceutical prazoles in environmentally friendly approach. In this work, the thermostable BVMO named PockeMO had high sulfoxidation activity towards rabeprazole sulfide to form (R)-rabeprazole but demonstrated significant overoxidation activity to form undesired sulfone by-product. To address this issue, the enzyme was engineered based on the computer assisted comparison for the substrate binding conformations.

Water-soluble porphyrins have garnered significant attention due to their broad range of applications in biomedicine, catalysis, and material chemistry. In this work, water-soluble platinum(II) and palladium(II) complexes with porphyrins bearing ethyl phosphonate substituents, namely, Pt/Pd 10-(ethoxyhydroxyphosphoryl)-5,15-di(-carboxyphenyl)porphyrins (M3m, M = Pt(II), Pd(II)) and Pt/Pd 5,10-bis(ethoxyhydroxyphosphoryl)-10,20-diarylporphyrins (M1d-M3d; aryl = -tolyl (1), mesityl (2), -carboxyphenyl (3)), were synthesized by alkaline hydrolysis of the corresponding diethyl phosphonates M6m and M4d-M6d. NMR, UV-vis, and fluorescence spectroscopy revealed that the mono-phosphonates M3m tend to form aggregates in aqueous media, while the bis-phosphonates M3d exist predominantly as monomeric species across a wide range of concentrations (10-10 M), ionic strengths (0-0.

Considering the demand for organosulfur materials and the challenges associated with currently used oxidation processes, in this study, we evaluated the counter-cation of sodium chlorite (Na+ClO2-) with tetrabutylammonium chloride (Bu4N+Cl-) to synthesise tetrabutylammonium chlorite (Bu4N+ClO2-). Bu4N+ClO2- exhibited good solubility in organic solvents like chloroform (1.6 g mL-1) and ethyl acetate (0.

Ionic liquid (IL) units in heterogeneous catalysts exhibit synergistic effects to enhance catalytic performance and stabilize catalytically active centers, while also preventing the degradation of catalysts during the reaction process. Ionic liquid units in IL-functionalized CMOF catalysts enhance their catalytic performance in a synergistic manner. However, not only are the yields of IL-functionalized CMOFs obtained with post-synthesis methods low, but they also lead to blocking of the MOF pores and leaching of the ionic liquid.

A Ce(III) phosphinate and a Ce(IV) phosphostibonate have been assembled by the reaction of a phosphinic acid and phosphostibonate with Ce(III) salts. Single crystal X-ray diffraction (SCXRD) studies reveal the formation of a rare triangular Ce(III) oxo-cluster [Ce(PhCHPO)]Cl(CHOH)(HO)] () and a fascinating hexanuclear oxo-cluster containing Ce(IV) ions [Ce (-ClCHSb)(μ-O)(μ-O)(-BuPO)(μ-OCH)] (). The molecular architecture of showcased an interesting correlation with platonic solids, wherein the Ce(IV), Sb(V), and P(V) ions were found to be present in vertices of an octahedron, a tetrahedron, and a cube, respectively.
