Conley, M.P., et al., A Well-Defined Pd Hybrid Material for the Z-Selective Semihydrogenation of Alkynes Characterized at the Molecular Level by DNP SENS. Chemistry, 2013. 19(37): p. 12234-8.
Direct evidence of the conformation of a Pd-N heterocyclic carbene (NHC) moiety imbedded in a hybrid material and of the Pd-NHC bond were obtained by dynamic nuclear polarization surface-enhanced NMR spectroscopy (DNP SENS) at natural abundance in short experimental times (hours). Overall, this silica-based hybrid material containing well-defined Pd-NHC sites in a uniform environment displays high activity and selectivity in the semihydrogenation of alkynes into Z-alkenes.
Selective editing of Val and Leu methyl groups in high molecular weight protein NMR
Selective editing of Val and Leu methyl groups in high molecular weight protein NMR
Abstract The development of methyl-TROSY approaches and specific 13Câ??1H labeling of Ile, Leu and Val methyl groups in highly deuterated proteins has made it possible to study high molecular weight proteins, either alone or in complexes, using solution nuclear magnetic resonance (NMR) spectroscopy. Here we present 2-dimensional (2D) and 3-dimensional (3D) NMR experiments designed to achieve complete separation of the methyl resonances of Val and Leu, labeled using the same precursor, α-ketoisovalerate...
