✦ Synopsis

Spectroscopic studies (IR, Raman, 'H and 13C NMR) on the complexes (&diket)Rh(olefin)2 (/3diket = dpm, tfac, dbm; olefin = ethylene, propene, vinyl chloride, vinyl acetate, methyl acrylate, styrene) have been carried out. The influence of the pdiketone l&and on the Rh-olefin bond supports the view that metal-to-olefin 71 back-bonding is predominant. The 'H NMR spectra of the (fl-diket)Rh(olefin)2 complexes show that 6HY depends on the nature of both the substituents on the /3-diketone and on the olefin .
