for the first time, dioxomolybdenum(vi) complex with the general formula [moo2l2] containing a n-o bidentate ligands (hl=2-(o-aminophenyl)- benzimidazole) has been used for the oxidation of sulfides. elemental analyses (carbon, hydrogen, nitrogen), ft-ir and uv-visble spectra and 1hnmr analysis agree well with the proposed stoicheiometry of the complex [moo2l2].  a variety of sulfides were smoo...

Metal-containing Schiff base/sulfoxides were developed as chiral ligands for Pd(II)-catalyzed asymmetric intramolecular allylic C–H amination reactions. The use of metal-containing base allows tuning the selectivity and reactivity Pd(II)-catalyst, whereby a base-Cu(II)/sulfoxide ligand in combination with Pd(OAc)2 showed best performance. Both internal terminal alkenes applicable, products obta...

α,β-Unsaturated amidines can be synthesized in high yield by rhodium(II) carboxylate catalyzed 1,2-H shift following denitrogenation of α-diazo amidines. Using a large ligand and an electron-poor N-sulfonyl group results exclusive Z-selectivity excellent suppressing side reactions involving intramolecular oxygen transfer.

This work demonstrates the use of multiple-step ligand injection affinity capillary electrophoresis (ACE) using two model systems: vancomycin from Streptomyces orientalis and carbonic anhydrase B (CAB, EC 4.2.1.1). In this technique a sample plug of receptor and non-interacting standards is injected by pressure and electrophoresed in a buffer containing a given concentration of ligand. The sequ...
