In situ small-angle neutron scattering (SANS) measurements of deuteride precipitation in well-annealed, undeformed single crystal Pd have been performed at room temperature to observe the morphology of the precipitate as the deuterium fraction was increased over a range of 0.005 to 0.097 [D] / [Pd]. Supporting measurements were made of the room temperature deuterium solubility isotherm in the s...

Methanolysis of 2,4,6-tri-O-benzoyl-2,3-dibromo-3-deoxy-D-altrono-1,5-lactone gave methyl 3-bromo-3-deoxy-2,4,6-tri-O-benzoyl-alpha-D-ribo-hex-2-ulofuranosonat e (3) and the anomeric mixture of the analogous 4,6-di-O-benzoyl derivative, having HO-2 free. Compound 3 was subjected to debromination with tributyltin hydride and tributyltin deuteride in the presence of 2,2'-azo-bisisobutyronitrile a...

The primary subject of this thesis is the study of solid hydrogen deuteride by infrared absorption up to a pressure of 159 GPa and at temperatures ranging from 4 K to 160 K. This work constitutes the first reported infrared study of hydrogen deuteride in the range of ultra-high pressures where phase transitions occur. A phase transition of orientational ordering, previously observed by Raman sc...

Deuterium labelling is used to show that the disproportionation of thioxanthylium salts involve transfer of a hydride, (deuteride) ion from the9-positionof one molecule of the compound, as its hydro], to the 9 - position of another molecule in the cation form
