摘要：
C-13 MAS NMR spectra of tropolone included in alpha- and beta-cyclodextrins are observed at various temperatures in order to study tautomeric proton transfer. The activation energy for tautomeric proton transfer is <39 and 50.5 kJ/mol for tropolone in alpha- and beta-cyclodextrins, respectively. Kinetic solid-state effects on the tautomeric proton transfer in tropolone are examined.
