butane-)thioate hydrobromides. The course of the concurrent reactions depends on the presence of substituents of the starting thiones and on the nature of the 4-substituent of the bromoacetophenones. Semiempirical Austin method 1 (AM1) and density functional theory (DFT) B3LYP computational studies for the interpretation of two concurrent reaction pathways are presented. Graphical Abstract
