The addition of acid chloride-AlCl3 complexes and of acyl triflates to several acetylenes has been performed. Evidence is given that these additions occur at least partly through a vinyl cation intermediate. In the case of aroyl chlorides or aroyl triflates the intermediate vinyl cation can be attacked by the aromatic nucleus of the aroyl group, leading to the formation of indenones. The difference
