Preparation and characterisation of cobalt (l) acyl compounds

The new cobalt (l) acyl compounds, [Co(PMe3)(CO)3(COMe)] 1, [Co(PPhMe2)(CO)3(COMe)] 2, [Co(P(4-Me-C6H4)3)(CO)3(COMe)] 3 and [Co(P(4-F-C6H4)3)(CO)3(COMe)] 4, have been prepared from [Na(Co(CO)4)]. The compound [Co(PCy3)(CO)3(COMe)] 5 has been prepared from [Co(PCy3)(CO)3(Me)] 6. The crystal structures of 5 and 6 are reported.
