Direct synthesis of pyridine and pyrimidine derivatives
I. Synthesis of Substituted Pyridine Derivatives via the Ruthenium-Catalyzed Cycloisomerization of 3-Azadienynes. The two-step conversion of various N-vinyl and N-aryl amides to the corresponding substituted pyridines and quinolines, respectively, is described. The process involves the direct …

An investigation of cation-exchange in aqueous pyridine
… acid resin Zeo-Karb 225, in aqueous and aqueous pyridine solutions of the alkaline earth metal cations. The ion-exchange phenomena investigated included: swelling, preferential sorption of solvent and selectivity variations with loading, degree of neutralization of the resin, solvent composition …

Deuterium Solid State NMR Studies of Pyridine Intercalation Compounds
… on polycrystalline samples of perdeuterated pyridine and selectively deuterated d$\sb2$-pyridine intercalated into 2H-TaS$\sb2$ was performed between 280K and 393K. The powder pattern lineshapes above 333K show signs of motional narrowing. A short spin-lattice relaxation (T$\sb1$) component, …

Studies on pyridine nucleotide-dependent processes in Haemophilus influenzae
… for externally-provided NAD; therefore, several pyridine nucleotide-requiring enzymes become important for the survival of these pathogens. Haemophilus influenzae ATP:NMN adenylyltransferase was partially purified 15-fold with a 27% yield using dye affinity chromatography. Affinity chromatography …

Synthesis and application of pinene-pyridine derivatives in asymmetric catalysis
… herein focuses on the synthesis of chiral pinene-pyridine derivatives, and their application in asymmetric catalysis. Both transition metal catalysed and organocatalytic transformations were investigated. Chiral pyridine-phosphines based on α-pinene were synthesised and applied as efficient …

An exploration of supramolecular tape-like assemblies formed by pyridine dicarboxylates
… previous survey of the solid-state behaviour of pyridinedicarboxylate diesters, an overview of which is presented in Chapter 1. These compounds have been shown to form tape-like assemblies, mediated by a novel triple hydrogen bond motif.<br/>Chapter 2 examines the behaviour of a small subset of …
