Low temperature matrix-isolation and solid state vibrational spectra of tetrazole [PDF]

, 2001
Infrared spectra of tetrazole (CN isolated in an argon matrix (T \10 K) and in the solid state (at room 4H2) temperature) were investigated. In the crystalline phase, tetrazole exists in its 1H-tautomeric form and new assignments of the vibrational ...

An Achiral Tetradentate Cis‐α‐Coordinating NCCN Ligand Gives Rise to a Configurationally Stable Chiral‐at‐Iron Complex for Enantioselective Catalysis

Chemistry – A European Journal, Volume 32, Issue 3, 16 January 2026.
The design and synthesis of a linear tetradentate NCCN ligand incorporating two 1,2,3‐triazolin‐5‐ylidene mesoionic carbene donors, and its application to asymmetric iron catalysis is reported. This work represents the first example of an iron complex derived from a cis‐α‐coordinating tetradentate NCCN ligand, and notably, the first chiral iron ...

Concise Synthesis of Tetrazole Macrocycle [PDF]

Organic Letters, 2017
A concise two step synthesis of tetrazole containing macrocycles from readily accessible starting materials is presented. The first step comprises a chemoselective amidation of amino acid derived isocyanocarboxylicacid esters with unprotected symmetrical diamines to afford diverse α-isocyano-ω-amines. In the second step, the α-isocyano-ω-amines undergo
