“…Various palladium diketonato complexes have been studied in an effort to determine what controls the linkage mode of the ligand. 49 The keto-enol character of the diketone was cited as the major factor governing the bonding type (0,0 or C). This theory was further expanded in a review on this subject.41 As applied to the osmium complexes, the keto-enol equilibrium correlates with the bonding observed in 17-23.…”
