Abstract

In situ IR and multinuclear NMR are used to monitor the formation of protonated diacetylketene tetrachloroaluminate (1) in the reaction of acetyl chloride and AlCl₃ in both dichloromethane and in 1-butyl-3-methylimidazolium chloride ([bmim]C1). The existence of a fast equilibrium between two enolic forms of protonated diacetylketene (with [AlCl₄]^- as the counterion) is established. The structure of 1 is determined by the rarely used ¹³C{¹H}-¹³C¹H} COSY experiment.
