Basicity Parameter of Weak Organic Bases,Derived from Thermodynamic Parameters of Their Reactions with (Tetraphenylporphyrinato)zinc(II)

摘要

The results of spectral and calorimetric studies of molecular adduct formation of porphyrin metal complexes with a wide series of bases (amines,amides,nitriles,ethers,aldehydes,ketones,alcohols,lactones,azoles,heterocyclic compounds,etc.) in organic solvents were systematized.From the thermodynamic parameters for complex formation of weak organic bases with (tetraphenylporphyrinato)zinc(II),a basicity parameter was derived which takes into account electron-donor and polarization properties of organic molecules,as well as steric coordination effects.
