Fourier transform infrared spectra of three titanium tetrachloride-ethyl benzoate complexes. Assignment based on five isotopic homologues and extension of the ethyl benzoate force field
摘要:
FTIR spectra (200-1750 cm-1) are given for (TiCl4EB)2, (TiCl4)2EB and TiCl4EB2, where EB is ethyl benzoate. A full assignment is given for (TiCl4EB)2 based on extension of an ethyl benzoate force field and four isotopically labelled complexes with O-18-carbonyl-EB, d5-EB, Ed5-B and d5-Ed5-B. There is no evidence for bidentate complexation or complexation through the ether oxygen in any of the complexes. A strong coupling between the a-C-O stretching vibration and the ethyl group deformations can make simplified interpretations of differences between spectra misleading.
