The relative concentrations of stereoisomers in product mixtures were determined as a function of time by using a combination of analytical techniques: vapor phase chromatography, polarimetry, NMR spectroscopy, and NMR spectroscopy in the presence of an optically active lanthanide shift reagent. The stereochemical reaction kinetics reveal that the Smith mechanism is not a plausible model for one-center epimerization; two trimethylenes, produced through two distinct cyclopropane C-C bond cleavages, are implicated, since all three possible one-center epimerizations are seen.

The reaction of diazocyclopentadienyl compounds with cyclomanganated arenes as a route to ligand-appended cymantrenes

The thermolysis of various cyclomanganated arenes in the presence of 5-diazocyclopentadiene, 7-diazoindene or 9-diazofluorene afforded the corresponding arenes tethered with cymantrenyl, benzocymantrenyl or dibenzocymantrenyl groups in fair to good yields. This reaction implies a multi-facetted mechanism that consists of three steps: the insertion of an alkylidene moiety into a C-Mn bond, a CAr-C bond formation and several haptotropic ring-slippages. The coupling reaction has proven to be particularly efficient with Mn(CO)4 chelates derived from acetylarenes and nitrogen-containing heterocycles. In one case of a 2-phenyl-2-oxazoline complex, the coupling with 9-diazofluorene yields a new η1-dibenzocymantrene complex in which the Mn(CO)4 moiety is chelated and is part of a six-membered metallacycle. The results of this study are mainly supported by the molecular structures of nine new complexes obtained by X-ray diffraction analyses. Wiley-VCH Verlag GmbH & Co.
