There is very little correspondence between the values of the thermodynamic parameters and the Pauling electronegativities of the elements. However, there is a crude correspondence with the oxophilicity scale developed by Kepp. Second, the condensation is generally more spontaneous and energetic for alkyl metals than for the corresponding metal chlorides. Third, the presence of electrondonating groups on the central metal decreases the driving force (increase ΔG) for the condensation.
