(tetrahydrofuran) at 703C for 16 h. The ester residue is then converted to a 6,6-dideuteriohexose residue, the O-methyl ethers of which are easily distinguishable by GC-MS of the derived alditol acetates. An alternative to acid hydrolysis that is applicable to most polysaccharides and glycoconjugates, including those containing acid-labile residues or glycosidic linkages resistant to hydrolysis...

Gas-liquid chromatography in the analysis of mercury (II) compounds.

Gas-liquid chromatography (GLC) in recent years has found application in the analysis of various metals, either singly (1) or in tandem function with mass spectrometry (2), and presently is gaining wide acceptance in the analysis of organomercury(II) compounds. Since increasing use of GLC in mercury analysis may be anticipated for both research and monitoring purposes, it is of value at this po...

Cruciaromaticity in organometallic compounds

A recent suggestion, that transition metal complexes of unsaturated ligands can be regarded as cruciconjugated, is explored by studies of various complexes of Fe(II), the aromaticity of the resulting i systems being analyzed in terms of PMO theory. This approach is also applied to porphyrin. The conclusions are supported by preliminary SCF and MNDO calculations.
