A study of the Pauson-Khand reaction (PKR) based on Co2(CO)8 and binap has revealed that a key precatalyst is (binap)Co2(CO)6, and that alkynes add to this species to generate isomers that interconvert under typical PKR conditions. A 31P NMR study of

Understanding the interaction of chiral ligands, alkynes, and alkenes with cobaltcarbonyl sources is critical to learning more about the mechanism of the catalytic, asymmetric Pauson-Khand reaction. We have successfully characterized complexes of the

N-Heterocyclic carbene derivatives of dicobalt octacarbonyl have been synthesized for the first time and tested in the Pauson−Khand reaction. Two complexes with both NHC and PPh3 ligands represent the only examples of structurally characterized dic

The synthesis and X-ray crystallographic characterization of a Pd complex (3) with a rigid C,N,C-tridentate pincer carbene ligand are described. At high temperatures (165 °C) it is an active and robust catalyst in the Heck reaction. Complex 3 gives

Methods are discussed for rapid screening of soluble and polymer-bound homo-geneous catalysts for activity. A polymer-bound phosphine library is synthesized, and a modular tridentate pincer CNC bis-carbene Pd complex is described. The possibility of

In a biomimetic approach to organometallic catalysis, pendant hydrogen-bonding groups are shown to influence the chemistry of ligand binding and activation in an iridium complex. Such groups can bind a substrate by hydrogen bonding and so offer the p

X-ray crystallographic analysis of red crystals formed on mixing octacarbonyldicobalt(0) and BINAP, combined with NMR evidence obtained from a catalytic asymmetric Pauson−Khand reaction, suggests that this complex is a precatalyst to this reaction
