Studies on Organic Microanalysis. XXIII

The Present Status of Organic Elemental Microanalysis

The influence of instrumental analysis, i.e., physicochemical methods, has become increasingly important in organic chemistry, but organic elemental microanalysis is by no means an obsolete field. On the contrary, with the development of new methods, the organic chemist obtains the results that he needs for a first orientation on a compound, more quickly and more reliably than ever before. Toda...

9 Titanocene and zirconocene complexes with a phenyl or I-naphthyl substituent in one ,B-position of each Cs-ring ligand and with an interannular tetramethylethanoor dimethylsilano-bridge have been prepared. Racemic complex isomers, which are formed together with varying amounts of their meso isomers, were separated from the latter and characterised by lH NMR spectroscopy and X-ray crystallogra...
