    Highly active and selective photochemical reduction of CO2 to CO using molecular-defined cyclopentadienone iron complexes
    (Cambridge : Soc., 2015) Rosas-Hernández, Alonso; Alsabeh, Pamela G.; Barsch, Enrico; Junge, Hernrik; Ludwig, Ralf; Beller, Matthias
    Herein, we report highly active (cyclopentadienone)iron–tricarbonyl complexes for CO2 photoreduction using visible light with an Ir complex as photosensitizer and TEOA as electron/proton donor. Turnover numbers (TON) of ca. 600 (1 h) with initial turnover frequencies (TOF) up to 22.2 min−1 were observed. Operando FTIR measurements allowed for the proposal of a plausible mechanism for catalyst activation.

    Enantio- and diastereoselective synthesis of γ-amino alcohols
    (Cambridge : Soc., 2015) Verkade, Jorge M. M.; Quaedflieg, Peter J. L. M.; Verzijl, Gerard K. M.; Lefort, Laurent; van Delft, Floris L.; de Vries, Johannes G.; Rutjes, Floris P. J. T.
    The γ-amino alcohol structural motif is often encountered in drugs and natural products. We developed two complementary catalytic diastereoselective methods for the synthesis of N-PMP-protected γ-amino alcohols from the corresponding ketones. The anti-products were obtained through Ir-catalyzed asymmetric transfer hydrogenation, the syn-products via Rh-catalyzed asymmetric hydrogenation.
