Conclusions

The change in hybridization of the two-carbon linker in a κ2_{-bis(diphenyl)phosphino ligand} attached to a cyclopentadienylcobalt(I) fragment has been found to stabilize this electron-rich oxidation state by 50 mV without affecting the rate constant plateau for protonation of “Co(I)” by strong (pKa < 16) acids. However, the linear free energy relationship for the protonation of

CpCo(I)(dppv) appears based on preliminary data to be substantially steeper than that of CpCo(I)(dppv). The modulation of such a linear free energy relationship by slight modification of a ligand’s structure is a promising avenue for improving understanding of the interplay between thermodynamics and kinetics in metal hydride formation.
