- Microwave alkylation of lithium tetrazolate
-
Abstract: N1-substituted tetrazoles are interesting ligands in transition metal coordination chemistry, especially in the field of spin crossover. Their synthesis is performed in most cases according to the Franke-synthesis, using a primary amine as reagent introducing the substitution pattern. To enhance flexibility in means of substrate scope, we developed a new protocol based on alkylation of lithium tetrazolate with alkyl bromides. The N1–N2 isomerism of the tetrazole during the alkylation was successfully suppressed by use of highly pure lithium tetrazolate and 30?vol.% aqueous ethanol as solvent, leading to pure N1-substituted products. The feasibility of this reaction was demonstrated by a selection of different substrates. Graphical abstract: [Figure not available: see fulltext.]

- REACTIONS OF TRIMETHYLSILYL AZIDE WITH ALDEHYDES: FACILE AND CONVENIENT SYNTHESES OF DIAZIDES, TETRAZOLES, AND NITRILES
-
The reactions of trimethylsilyl azide (TMSA) with various aldehydes were found to be versatile procedures for the synthesis of gem- and 1,3-diazides, tetrazoles, and nitriles, whose formation was varied by controlling the quantities of TMSA, catalyst, and the reaction conditions.

- SYNTHESIS OF 1-SUBSTITUTED TETRAZOLES BY HETEROCYCLIZATION OF PRIMARY AMINES, ORTHOFORMIC ESTER, AND SODIUM AZIDE
-
It has been shown that the reaction of heterocyclization of primary amines with orthoformic acid and sodium azide in acetic acid has a rather general character and is a convenient method for the synthesis of 1-substituted tetrazoles.On the basis of experimental data, a probable reaction mechanism is proposed.
