摘要
DFT methods are used to quantify the relationship between M-C and H-C bond energies; for MLn = Re(eta(5)-C5H5)(CO)(2)H and fluorinated aryl ligands, theoretical and experimental investigations of ortho-fluorine substitution indicate a much larger increase in the M-C than in the H-C bond energy, so stabilising C-H activation products.
