MONONUCLEAR ALKYL AND ACYL DERIVATIVES OF RHENIUMPENTACARBONYL - SYNTHESIS, CHARACTERIZATION AND PROPERTIES

The extensive homologous series of acyl and n-alkyl compounds, [Re(COR )(CO)(5)] and [Re(R)(CO)(5)](R=CH3 to n-C18H37), has been synthesized. The majority of the compounds are new and have been fully characteriz ed by elemental analysis, IR, H-1 and C-13 NMR and mass spectrometry. The data for the series are discussed. Some properties of the compound s are described, including reactions of the alkyl compounds with PPh(3 ), which yield cis-[Re(R)(CO)(4)(PPh(3))] and not cis-[Re(COR)(CO)(4)( PPh(3))] as might have been expected.
