摘要：

The formation constants and the enthalpies of formation of CH/pi complexes were determined for a series of ternary chloroform/aromatic pi-base/carbon tetrachloride (solvent) systems. The enthalpies showed that the interaction is favored by the electron-releasing substituent on the aromatic ring. Electronegative substituents on the CH donor also strengthen the interaction. The fact renders a support on the hydrogen-bond-like nature of the CH/pi interaction.
