where𝑓 are the condensed Fukui functions and 𝜔 is the global electrophilicity index. Details on the global reactivity indices and the condensed Fukui functions calculated in this work are reported in Section S3. According to their definition, a greater 𝜔 6 8 value corresponds to a better capability of accepting electron density, whereas a smaller value of 𝜔 6 " makes it a better donor of electron density. To equalize the notions and to obtain a descriptor for local nucleophilicity for which high value corresponds to high tendency at donating electron density, a nucleophilicity index 𝑁 6 was proposed as the inverse of 𝜔 6 " ∶ 78
