SYNTHESIS AND REACTIVITY OF CARBON-BONDED TRANSITION ELEMENTS
New experimental results recently obtained in this and other Laboratories are presented. These results suggest the following hints for further research :a) apparently slight modifications in the donor atoms set around a metal can alter the energetic situation considerably at the metal-carbon bond; b) the molecular parameters obtained by diffraction studies should always be complemented by studies of reactivity and/or of spectral behaviour in solution in order to have a reasonable description of a chemical species.
