摘要
The results of extended X-ray absorption fine structure (EXAFS) spectroscopic investigations and supporting theoretical MNDO/AM1/PM1 calculations for a model system of Friedel-Crafts alkylation (benzene, nitrobenzene, AlX(3) where X = Cl or Br, CH3CH2Br) are presented. Detailed structural models for the system are deduced with the help of the EXAFS-determined distances. The conclusions drawn from the EXAFS data are confirmed by the results of the theoretical calculations.
