1,3-Phenylene-bis-(1H)-tetrazole pincer ligand for palladium-catalyzed Suzuki cross-coupling reactions of arylhalides with arylboronic acids

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.

Efficient copper-catalyzed cyanation of aryl bromides using 1,3-phenylene-bis-(1h)-tetrazole as an efficient ligand

A new method for the synthesis of aryl nitriles has been developed by the cyanation of aryl bromides with K4Fe(CN)6 as a cyanide source in the presence of Cu(OAc)2.H2O as an inexpensive catalyst and a 1,3-phenylene-bis-(1H)-tetrazole ligand. This method has the advantages of high yield, simple methodology and easy work-up.

α-Ferrocenylation of Tetrazole and Its 1-substituted Derivatives in Two-Phase Systems

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.

SYNTHESIS AND PROPERTIES OF PHENYLENEBIS-1H-TETRAZOLES

Heterocyclization of m- and p-phenylenediamines with orthoformic ester and sodium azide has given phenylenebis-1H-tetrazoles.Under these conditions, o-phenylenediamine gives benzimidazole. o-, m-, and p-Phenylenebis-1H-tetrazoles were also obtained from the nitroanilines via the intermediate nitro- and aminophenyltetrazoles.The reactions of the bistetrazoles examined were basic hydrolysis, aminomethylation, and complex formation with copper salts.
