The reactions of arene-metal complexes (arene = p-cymene, benzene or pentamethylcyclopentadienyl, metal = Ru, Rh or Os), including 1,3,5-triaza-7-phosphatricyclo-[3.3.1.1]decanephosphine (pta) and chloro co-ligands, with 9-methylguanine, adenine, and a ser ...
In analogy to the authors' successful PX2+ insertion reactions, an AsX2+ insertion route was explored to obtain new arsenic halogen cations. Two new salts were prepd.: AsBr4+[Al(OR)4]-, starting from AsBr3, Br2 and Ag[Al(OR)4], and I2As-PI3+[Al(OR)]4 from ...
Reactions of the dinuclear ruthenium complex [(p-cymene)Ru(mu-Cl)3RuCl(C2H4)(PCy3)] with phenylacetylene or tert-butylacetylene gave the vinylidene complexes [(p-cymene)Ru(mu-Cl)3RuCl(=C=CHR)(PCy3)] (R = tBu, Ph), which were characterized crystallographica ...
In order to relate the conformational dynamics of the hammerhead ribozyme to its biological function the cleavage reaction catalyzed by the hammerhead ribozyme was monitored by time-resolved nuclear magnetic resonance (NMR) spectroscopy. For this purpose, ...
The investigation of H-1-H-1 spin-diffusion build-up curves using a rate matrix analysis approach shows that high-resolution magic angle spinning NMR of protons, applied to powdered organic compounds, provides a method to probe crystalline arrangements. Th ...
A unified strategy for the synthesis of mauritines A (I), B, C, and F has been developed based on a key intramol. nucleophilic arom. substitution reaction (SNAr) for the formation of the strained 14-membered paracyclophane. It was demonstrated that the out ...
Throughout the paper, the incorrect reagent names "phosphorus tribromide" and "phosphorus trichloride" should be replaced by the correct names "phosphoric tribromide" (POBr3) and "phosphoric trichloride" (POCL3). [on SciFinder (R)] ...
4-benzoylpyridine thiosemicarbazone (H(4)Bz(4)DH) and N(4')-phenyl-4-benzoylpyridine thiosemicarbazone (H4Bz4Ph) were obtained and fully characterized by infrared, UV and NMR spectroscopies. The assignment of the NMR signals was made by using DEPT135 and t ...
The molecular forms of LiF, LiFHF and Na2SiF6 have been stabilized using trinuclear metallamacrocyclic complexes of (cymene)Ru-II, (Cp*)Rh-III and (Cp*)Ir-III as specific receptors. The host-guest complexes were characterized by NMR spectroscopy and single ...
A two-dimensional proton-mediated carbon-carbon correlation experiment that relies on through-bond heteronuclear magnetization transfers is demonstrated in the context of solid-state NMR of proteins. This new experiment, dubbed J-CHHC by analogy to the pre ...
