Stable cis-hydrldoacylrhodlum complexes, cis-HRh(COR)(PMe3)3Cl (R = Me, Ph, 4-C6H4F, OMe), are obtained by oxidative addition of RCHO to RhCl (PMe3)3 (1). Upon heating, these complexes undergo competing intramolecular reductive elimination of the aldehyde and decarbonylation to the alkane; the former process prevails if RCHO is removed as formed. Both these processes proceed from a common unsaturated intermediate, formation of which is probably rate determining.
