One-step synthesis of vicinal bromoiodoenamides from ynamides through IBr addition is described. Two types of IBr were used: commercially available IBr, and in situ generated IBr. This simple protocol enables highly efficient regio- and stereoselective iodobromination of the triple bond on a gram scale in anti-mode, and provides a potentially diverse scaffold for preparation of tetrasubstituted olefins
