摘要：

C-13, Al-27 and O-17 NMR investigations about the nature of the 1:1 system AlCl3.RCOCl (R = CH3, CH2Cl, CHCl2, CCl3) in CH2Cl2 show a donor-acceptor structure with the carbonyl oxygen involved in the metal co-ordination. The shift of the carbonyl group resonance (DELTA-delta) in C-13 and O-17 NMR spectra is strongly dependent on the electron-withdrawing power of the R group and shows a close connection with the reactivities of the different acyl complexes.
