Abstract
The equimolar complex of acetyl chloride and gallium trichloride has been prepared and its infrared spectrum, both in the pure state and in nitrobenzene solution, has been recorded. In the pure complex a strong band at 2300 cm−1, hitherto attributed to the acetylium ion, has been observed. In solution in nitrobenzene, the 2300 cm−1 band is almost completely replaced by one at 2200 cm−1, while undissociated CH3COCl is present. Certain bands in this spectrum are consistent with the presence of the nitrobenzene – gallium chloride complex. A re-evaluation of the assignments of the acetylium ion suggests that a more complicated ionic species may be present in the solid state, possibly [CH3CO … GaCl3]+Cl−.Keywords
