Developments in Pd Catalysis: Synthesis of 1H‐1,2,3‐Triazoles from Sodium Azide and Alkenyl Bromides

Another star for the Palladium: The discovery of reactions promoted by the ubiquitous Pd0 catalysts is still possible. 1H-1,2,3-Triazoles are directly obtained by reaction of alkenyl bromides and sodium azide in the presence of a Pd0–xantphos catalyst (see scheme, xantphos=9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene, dba=trans,trans-dibenzylideneacetone).
