Different gold catalysts effect either selective bromine migration or hydrogen shift in haloallenyl ketones, leading to the formation of 3- or 2-bromofurans, respectively. AuCl3-catalyzed transformations include 1,2-halogen migrations via proposed halirenium intermediates and allow for mild and efficient synthesis of various types of 3-halofurans.
