Substituent Effects on 13c Nmr Chemical Shifts in Dialkylaminophenylchlorophosphines
The relative chemical shifts and 2J(PC) coupling constants in the low-temperature limiting spectra of a series of Ph(R,N)PCl compounds [R = Me, Et, PhCH2, ‘Pr and c-Hex] differ for R = primary or secondary. For primary alkyl substituents, the more downfield signal exhibits a large, positive coupling and the more upfield resonance shows a small, negative coupling. These observations are reversed...
متن کاملComputed 13C NMR Chemical Shifts via Empirically Scaled GIAO Shieldings and Molecular Mechanics Geometries. Conformation and Configuration from 13C Shifts
Accurate (rms error ∼3 ppm) predictions of 13C chemical shifts are achieved for many of the common structural types of organic molecules through empirical scaling of shieldings calculated from gauge including atomic orbitals (GIAO) theory with a small basis set and with geometries obtained from computationally inexpensive molecular mechanics methods. Earlier GIAO calculations are shown to be mu...
متن کامل15N_, lH_, and 13C-NMR Chemical Shifts and Electronic Properties of Aromatic Diamines and Dianhydrides
We measured the 15N -, 1 H -, and l1C_ NMR chemIcal shIfts for a senes of aromatIc dlammes and aromatIc tetracarboxyhc dlanhydndes dIssolved m DMSO-db , and dIscuss the relatIOnshIps between these chemIcal shIfts and the rate constants of acylatIOn (k) as well as such electronIc-property-related parameters such as IOnIzatIOn potentIal (IP), electrOnIc affinIty (EA), and the energy E of the hIgh...
متن کاملDependence of 13C NMR chemical shifts on conformations of rna nucleosides and nucleotides.
Cross-polarization magic-angle spinning solid-state NMR spectroscopy has been used to investigate the dependence of (13)C sugar chemical shifts on specific conformational parameters of a variety of ribonucleotides and ribonucleosides. Solid-state NMR is a valuable tool for nucleoside and nucleotide structural studies since it provides the means to acquire spectra that correspond to single confo...
متن کاملDFT calculations of 1H and 13C NMR chemical shifts in transition metal hydrides.
Transition metal hydrides are of great interest in chemistry because of their reactivity and their potential use as catalysts for hydrogenation. Among other available techniques, structural properties in transition metal (TM) complexes are often probed by NMR spectroscopy. In this paper we will show that it is possible to establish a viable methodological strategy in the context of density func...
