A one‐pot procedure for the synthesis of 5‐substituted 1 H ‐tetrazoles through the three‐component reaction between an aryl bromide, potassium hexakis(cyano‐ κC )ferrate(4−) (K 4 [Fe(CN) 6 ]) and NaN 3 catalyzed by [Pd(OAc) 2 ] and ZnBr 2 in the presence of 1,4‐diazabicyclo[2.2.2]octane (dabco) was developed. Furthermore, the reaction occurred under nonacidic conditions and involved a nontoxic cyanide source, making this method a quite attractive one.
