The interactions of alkali fluorides with D-xylose have been studied by X-ray diffraction (XRD), infrared spectroscopy (IR), nuclear magnetic resonance (NMR, 1H and 13C) and atomic absorption spectrophotometry. KF and CsF form complexes with D-xylose in a 1:1 molar ratio.

Benzylammonium N-alkylides were generated by reaction of N-[1-(trimethylsilyl)alkyl]benzylammonium salts with cesium fluoride in DMF or HMPA, and their rearrangement products were investigated. [2,3]Sigmatropic rearrangement of the ylides initially occurred to give isotoluene derivatives and then they were transformed into Sommelet-Hauser

Ten DNA fragments containing self-complementary alternating sequences of adenine and thymine differing in length and the starting nucleotide were studied by c.d. spectroscopy. It was found that d(TATATATA) but not d(ATATATAT), d(TATATA), d(CTATATAG) or (dT-dA)20 isomerized into the unusual X-DNA

The effect of intracellular fluoride ions on voltage-dependent calcium currents was tested during whole-cell voltage-clamp recordings in thalamic neurones acutely dissociated from young adult rats. It is demonstrated that 5-30 mM intracellular fluoride selectively and reversibly suppresses the high voltage-activated
