The Equilibria and the Entropy Correction

• Halogenophilicity
  1. ^N[N,N]FeCl₂ + Cl-CH₂-Ph = ^N[N,N]FeCl₃ (quartet) + •CH₂Ph,
     ΔS = -5.5,ΔΔH = 1.6 kcal/mol
  2. ^N[N,N]FeCl₂ + Cl-CH₂-Ph = ^N[N,N]FeCl₃ (sextet) + •CH₂Ph,
     ΔS = -5.0, ΔΔH = 1.5 kcal/mol
• Carbophilicity
  1. ^N[N,N]FeCl₂ + •CH₂-Ph = ^N[N,N]FeCl₂CH₂Ph (sextet),
     ΔS = -43.1, ΔΔH = 12.9 kcal/mol
