Graphite intercalation compounds were prepared from flakes of natural graphite and Thornel P-120 carbon fibers. Stage 2 compounds were obtalned with TaCI, at 400 C, and stage 4 compounds with NbClj at 200 C. The compounds with TaCI, were stable in amblent air or under water at 25-C. At 90 C with wat
## Abstract The composition of the mixture from the reaction of the basic amino acids ornithine or lysine with pyridoxal‐5′‐phosphate was investigated in D~2~O by ^1^H NMR and was found to be dependent on pH, α attack being favoured at acid pH and ω attack in basic solutions.
The tetrazole-azide tautomerization of some halogen-substituted tetrazolo [1,5-a]pyridines was examined by IR spectroscopy at ambient temperature and by 1 H, 13 C and 15 N NMR spectroscopy at various temperatures. The tetrazolopyridines can exhibit equilibrium between the azide and the tetrazole for
