Sometimes chemists set themselves up for a surprise. Following sets of experiments in which something doesn’t happen and doesn’t seem likely to happen, they soon believe it never will. Until it does.

Chemical modifications that introduce chiral features to cyclopentadienyl (Cp) ligands have allowed two research teams to carry out rhodium-catalyzed C–H functionalization reactions to prepare ...

years after the discovery of ferrocene, stable metallocenes have now been made with all of the 3d transition metals ...

CYCLOPENTADIENONE complexes of several transition metal ions have been prepared by the reaction of hexa-fluoro-but-2-yne with the metal carbonyl or π-cyclopentadienyl metal carbonyl 1. Detailed ...
