A 100,000-Fold Increase in C-H Bond Acidity Gives Palladium a Key Advantage in C(sp³)-H Activation Compared to Nickel
This study directly compares the C-H bond weakening abilities of nickel and palladium, finding that palladium acidifies C(sp³)-H bonds 100,000 times more than nickel. This acidification makes palladium a preferred metal in C(sp³)-H functionalization reactions.
