In recent years, palladium free cross couplings such as the Ullmann reaction have gained in popularity due to their cost-effectiveness . Ullmann couplings, in particular are a viable option for aryl bromide / iodide and nucleophile cross couplings. The Ullmann dataset is more modest in scope and scale than its Buchwald-Hartwig counterpart, at about half the size, however even in this smaller space HiTEA is applicable.
