  A Comprehensive Study on Infrared Spectra of 2-Hydroxyxanthone

  摘要：

  A study on the IR spectra of 2-hydroxyxanthone that was both experimental and theoretical was carried out in this work. The optimized structure and related spectral parameters were obtained by using the Becke-3-Lee-Yang-Parr (B3LYP) method with the 6-31G* and 6-311G** basis sets. The corresponding geometrical parameters were compared with each other. Detailed assignments of the vibration frequencies were performed. The agreement between the scaled theoretical frequencies and the observed frequencies was found to be quite good. Also, the calculation accuracies of the two basis sets are close.

  Two at once: Xanthones with different functional groups were obtained with CO (balloon) in the presence of a simple catalytic system that consists of Pd(OAc)2, K2S2O8, and trifluoroacetic acid (see scheme). Preliminary mechanism studies reveal that the second CH functionalization might be the rate‐determining step.

  Oxygenation of cyclic diphenyl iodoniums (CDPIs) with varied medium‐ring sizes has been fully investigated. This practical copper‐catalyzed tandem reaction of CDPIs with water as the oxygen source enables the construction of derivatised dibenzofurans and xanthenes at moderate to good yields. Moreover, structurally important xanthones are also successfully accessed under the oxygenation conditions with
