Abstract

The absolute stereochemical configurations of a series of optically pure alkyne-Co2(CO)5PPh3 complexes and their corresponding cyclopentenones, derived from Pauson-Khand reaction with norbornene, have been established; an X-ray crystal structure of an optically pure cyclopentenone has facilitated this study. In turn, this has led to the unambiguous determination of the site of decarbonylation and alkene complexation when such monophosphine complexes are utilised in asymmetric Pauson-Khand processes.
