According to log k20°C = sN(N + E)

Currently the database contains the reactivity parameters of 1075 nucleophiles and 281 electrophiles.

News: Beta version of 'Mayr's Database of Reactivity Parameters' (Database 2.0) has been launched.

Covered nucleophilicity range: -8.80 ≤ N ≤ 28.95
Covered electrophilicity range: -24.60 ≤ E ≤ 8.02
