    Description / Table of Contents: Reaktionen von Acetylbromid mit Lewis-Säuren. I. Raman-Untersuchung der Systeme MCl4—CH3COBr (M = Ti, Sn)Die Systeme MCl4—CH3COBr (M = Ti, Sn) wurden durch ihre Raman-, infrarot- und kernmagnetische Resonanzspektren untersucht. Die zwei letzteren Methoden zeigen, daß weder der acetylion, CH3CO+, noch der TiClxBry komplex vorhanden sind. Die Zuordnung der Ramanspektren erfolgt auf Grund der Annahme, daß Halogenaustausch zwischen MCl4 und CH3COBr zu MBr4 und CH3COCl, und zu gemischten Derivaten der Typus MClxBr4-x führt. Veränderungen der Redoxzustände werden hierbei nicht beobachtet.
    Notes: In order to study the systems MCl4—CH3COBr (M = Ti, Sn), the Raman, infrared and PMR spectra of a number of solutions MX4 + R CH3COY in CCl4 ({X, Y} = {Cl, Cl}, {Br, Br}, {Cl, Br}) have been recorded. The PMR and i.r. studies show the absence of both CH3CO+ ion and the oxo-donor species. The Raman spectra are consistent with an halogen exchange between MCl4 and CH3COBr, leading to MBr4 and CH3COCl, and all the mixed halides MClxBr4-x. No redox reaction was observed.
