    • N2 reactions, where the steric hindrance between substituents in such backside-attack raises the energy of the transition state (below). Also in equilibria of Lewis acid-Lewis base complexation, such as in R 3 ′ N - BR 3 adduct formation, greater F-strain between the R and R′ groups promotes complex dissociation. Cf. M.S.
