Treatments of various nitriles with TMSN3 and Bu2Sn(OAc)2 at 30 °C in benzene for 60 h yielded the corresponding 5-substituted 1H-tetrazoles in good to excellent yields. This method is a mild and efficient alternative reagent system for Wittenberger tetrazole-synthesis that uses TMSN3 and Bu2SnO in toluene at high temperature (93–110 °C) for 24–72 h.

Efficient transformations of inactive nitriles into 5-substituted 1H-tetrazoles in DMF in a microwave reactor are described. The present method is applied to the synthesis of tetrazolato-bridged dinuclear platinum(II) complex and tetrazole C1-ribonucleoside phosphoramidite. Georg Thieme Verlag Stuttgart, New York.

Novel C5-linked C0- and C2-tetrazole ribonucleoside phosphoramidites were designed and synthesized via tetrazole C-nucleosides. Pivaloyloxymethyl (POM) and methyl-substituted POM (MePOM) groups were introduced as N-protecting groups in the tetrazole ring that can be readily removed under mild basic conditions. The phosphoramidites were successfully incorporated into the VS ribozyme substrate and hence providing a chemogenetic approach to determine which nucleobases of ribozymes function as the acid or base, in the studies of ribozyme general acid and base catalysis.
