Moderhack, Dietrich published the artcile< N-unsubstituted tetrazolocarboxaldehyde>, Application In Synthesis of 6136-93-2, the main research area is tetrazolecarboxaldehyde; aldehyde tetrazolyl.
The title compound was prepared by the cyclization of (EtO)2CHCN with N3H in the presence of pyridine to give I [R = CH(OEt)2], which was treated with HCl to give the aldehyde, which exists in the solid form as the dimer II. Upon dissolving in dry Me2SO at 80°, II gave 90% I (R = CHO), which undergoes most of the normal aldehyde reactions, e.g., aldol condensation. Reaction of I (R = CHO) with piperidine gave the unstable salt III, which upon exposure to air gave IV.
