摘要:

The development of organometallic chemistry over the past 25 years has led to extremely selective catalytic systems and to a greater understanding of their mechanisms. One area of particular interest has been the study of hydrogenation reactions (e.g. dienes to monoenes) using (η6−arene)tricarbonylchromium(0) complexes as catalysts.1–4The possibility of the catalytic liberation of functionalized arenes from the chromium centers in such compounds has also attracted the attention of synthetic organic chemists.5−6

摘要:

The discovery of molecular hydrogen coordination to transition metals and its significance in terms of reactions of σ bonds at metal centers and catalysis is described. The fact that several complexes, known for many years, have only now been shown to contain H2ligands after our finding, perhaps best reflects how surprising and well hidden this phenomenon has been. The existence of a tautomeric-like relationship between dihydrogen and dihydride ligands was equally unexpected. Diagnostics for, properties of. and induced cleavage of H2ligands are given, along with a bonding model in harmony with these properties.

摘要:

The magnetic properties of spin-crossover iron(III) complexes with N402ligands are reviewed and especially the rapid spin-state interexchange is discussed on the basis of absorption, ir, epr and Mössbauer spectra. Results from single crystal X-ray structure determination, kinetics and dilution experiments are also reported.
