Journal ArticleDOI
Ethylene/Norbornene Copolymerizations with Titanium CpA Catalysts
TL;DR: In this paper, the reaction temperature of CpA catalysts was determined at 40 °C for a copolymerization of poly(ethylene-co-norbornene) copolymers with a variety of α-olefins.
Journal ArticleDOI
Theoretical and empirical calculations of the carbon chemical shift in terms of the electronic distribution in molecules
TL;DR: In this paper, the principles of the theoretical calculations of the carbon atom screening constant are reviewed, and various empirical correlations which make an evaluation of δ13C from structural and physical properties possible are shown.
Journal ArticleDOI
Configurations and conformations in acyclic, unsaturated hydrocarbons. A 13C NMR study
J.W. de Haan,L.J.M. van de Ven +1 more
TL;DR: In this article, the differential shieldings of di- and trisubstituted ethylenes have been measured and the results are qualitatively in agreement with conclusions reached in previous 1H NMR (PMR) investigations, with the possible exception of 2,5-diMe-3-hexene.
Journal ArticleDOI
13C NMR of polycyclic aromatic compounds. A review
TL;DR: The analysis of the 13C NMR spectra of polycyclic aromatics is discussed in this article, where the influence of steric effects, bond order, mesomerism and angle distortions in relation to some of these coupling constants is discussed.
Journal ArticleDOI
Azide and Cyanide Displacements via Hypervalent Silicate Intermediates
Eric D. Soli,Amy S. Manoso,Michael C. Patterson,Philip DeShong,David A. Favor,Ralph Hirschmann,Amos B. Smith +6 more
TL;DR: Primary and secondary alkyl halides and sulfonates undergo rapid and efficient azide or cyanide displacement in the absence of phase transfer catalysts with the silicate derivatives, and application of these reagents to the stereoselective synthesis of glycosyl azide derivatives is reported.
