aryl- and heteroaryl-halides (bromides and iodides) to 5-aryl- and 5-heteroaryl-1H-tetrazoles. The conversion entails a copper(I) iodide co-catalyzed Stille palladium-catalyzed cross-coupling reaction and a N-benzyloxymethyl deprotection step. Coupling was possible with electron neutral and electron poor substrates in yields ranging from 35–93%.
