The complexes were characterized by NMR (31P{1H}, 1H and 13C), vibrational spectroscopy (FTIR), cyclic voltammetry, molar conductivity, UV-Vis and elemental analysis (%C, %H, %N, and %S). Furthermore, the molecular structure of complexes 1 and 2 were solved by X-ray diffraction studies. UV-Vis spectroelectrochemistry studies were carried out for complex 2 in order to unravel the processes observed in the cyclic voltammetry. DFT analysis of complexes 1, 2 and the precursor complex cis-[RuCl2(bipy)(dppf)] revealed the composition of the frontiers orbitals, supporting the assignment of the electrochemical behavior of the complexes. The antibacterial potential of the new complexes and the free ligands (dppf, mctz? and mcbtz?) were assessed in vitro against Staphylococcus aureus, Staphylococcus epidermidis, E. coli and P. aeruginosa.

Stereocontrolled Csp3 cross-coupling can fundamentally change the types of chemical structures that can be mined for molecular functions. Although considerable progress in achieving the targeted chemical reactivity has been made, controlling stereochemistry in Csp3 cross-coupling remains challenging. Here we report that ligand-based axial shielding of Pd(II) complexes enables Suzuki-Miyaura cross-coupling of unactivated Csp3 boronic acids with perfect stereoretention. This approach leverages key differences in spatial orientation between competing pathways for stereoretentive and stereoinvertive transmetalation of Csp3 boronic acids to Pd(II). We show that axial shielding enables perfectly stereoretentive cross-coupling with a range of unactivated secondary Csp3 boronic acids, as well as the stereocontrolled synthesis of xylarinic acid B and all of its Csp3 stereoisomers. We expect these ligand design principles will broadly enable the continued search for practical and effective methods for stereospecific Csp3 cross-coupling.

The sustainable synthesis of relevant scaffolds for their use in the pharmaceutical, agrochemical, and materials sectors constitutes one of the most urgent challenges that the chemical community needs to overcome. In this context, the development of innovative and more efficient catalytic processes based on a fundamental understanding of the underlying reaction mechanisms remains a largely unresolved challenge for academic and industrial chemists. Herein, selected examples of computational and experimental knowledge-driven approaches for the rational design of transition-metal-catalyzed transformations are discussed.

A series of iron dinitrosyl complexes of the form Fe(NO) 2(P(C6H4X)3)2 (X = p-OMe (1), p-Me (2), m-Me (3), p-H (4), p-F (5), p-Cl (6), p-CF3 (7)) has been prepared from the reactions of Fe(NO)2(CO)2 and the respective triarylphosphines. Complexes 1-7 have been characterized by IR and 31P NMR spectroscopy, and by X-ray crystallography for 1 and 7. In general, the compounds with the more basic phosphines display lower upsilonNO stretches in the IR spectra than those with the less basic phosphines, and the trends in upsilonNO as a function of Hammett parameter and solvent donor/acceptor number were analyzed. The redox behavior of compounds 1-7 in CH2Cl2 were studied by cyclic voltammetry at a Pt electrode. In general, the compounds undergo one-electron oxidations. Infrared spectroelectrochemistry revealed that the oxidations generate the derivatives with upsilonNOs that are ?100 cm -1 higher in energy indicative of Fe(NO)2-centered oxidations.
