A range of diastereomeric alkynepentacarbonyldicobalt complexes containing the (R)-(+)-Glyphos ligand have been prepared in moderate to good yields under standard thermal conditions. Additionally, novel tertiary amine N-oxide mediated reactions have been developed which allow the synthesis of the same range of complexes at room temperature with good selectivity in consistently high yields. Optically pure (R)-(+)-Glyphos containing complexes have been obtained by preparative HPLC separation of the sets of diastereomeric compounds. Finally, the amine N-oxide techniques allow the rapid and clean preparation of alkynepentacarbonyltriphenylphosphinedicobalt complexes in good to high yields at room temperature.

The preparation of alkynepentacarbonyltriphenylphosphinedicobalt complexes under mild conditions using linearly polarised ultra violet laser light is described. This method compares favourably with conventional thermal techniques and is superior when the alkyne contains reactive functional groups.
