Abstract

The combination of ATR-IR and modulation spectroscopy allowed for the study of the interaction of ketopantolactone with Pt/Al2O3 films chirally modified by cinchonidine under hydrogenation conditions. The spectra reveal a significant influence of ketopantolactone on the adsorption of the modifier and indicate a N-H-O hydrogen bond between modifier and reactant. The latter was corroborated by a comparative study with N-methyl cinchonidine chloride modified Pt/Al2O3.

摘要

衰减全反射红外光谱（ATR-IR）与调制光谱相结合，能够研究在氢化条件下，酮泛内酯与由辛可尼定进行手性修饰的Pt/Al₂O₃薄膜之间的相互作用。光谱显示，酮泛内酯对修饰剂的吸附有显著影响，并表明修饰剂与反应物之间存在N-H-O氢键。通过与氯化N-甲基辛可尼定修饰的Pt/Al₂O₃进行对比研究，证实了后者。
