Substituted phenones II reacted with ethylene glycol and pyridinium perbromide, phenyltrimethylammonium tribromide, or dioxane dibromide give the corresponding α-bromoacetals I. The highest yields are obtained with dioxane dibromide, and a route is suggested in which the agent is generated in situ. The mass spectra of the compounds I are interpreted.
