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

Four (binap)(enyne)tetracarbonyldicobalt(0) complexes have been synthesised and their reactivity monitored by variable temperature (31)P NMR spectroscopy. Formation of (binap)dicarbonylhydridocobalt(-1) 12 occurred at temperatures between 35 and 55 d

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

Heating (alkyne)(binap)tetracarbonyldicobalt(0) complexes bearing pendant alkenes leads to cleavage of the cobalt−cobalt bond and generation of the mononuclear hydride (binap)(CO)2CoH at 45−55 °C.
