1,3-Phenylene-bis-(1H)-tetrazole pincer ligand was synthesized by the reaction of 1,3-phenylenediamine, sodium azide and triethyl orthoformate in acetic acid and successfully used in Suzuki cross coupling reactions of aryl halides with aryl boronic acids.

Reactions of α-ferrocenylalkyl alcohols with tetrazole and its 1-substituted derivatives in two-phase systems of methylene chloride-aqueous solutions of HX acids (X = BF4, ClO4) result in the formation of 4-α-ferrocenylalkylated tetrazolium salts as the only isomers. Under the action of alkali reagents in aqueous media monosubstituted tetrazolium salts are converted into mixtures of 1- and 2-α-ferrocenylalkyl tetrazole derivatives, while disubstituted salts decompose to give the starting compounds when heated in 10% aqueous solution of sodium hydroxide. In the anhydrous medium, heating of 1-phenyl-5-ferrocenylmethylenetetrazolium fluoborate with t-BuOK in dioxane results in a rearrangement which proceeds by an ilide-type mechanism to form 1-phenyl-5-ferrocenylmethylenetetrazole. The latter reacts in the two-phase system with ferrocenylmethanol to give the corresponding trisubstituted tetrazolium salt.
