Pendem, Venkata Bhavanarushi published the artcileIron-promoted sulfur sequestration for the substituent-dependent regioselective synthesis of tetrazoles and guanidines, SDS of cas: 3696-23-9, the publication is Journal of Sulfur Chemistry (2021), 42(5), 499-509, database is CAplus.
Herein, a facile and versatile synthetic methodol. for the construction of tetrazoles and guanidines in the presence of an eco-friendly, inexpensive and easily available iron reagent were established. Aromatic thioureas with electron-donating substituents produced their resp. target products in quant. yield. In contrast, when electron-withdrawing substituted aromatic thioureas were used, the expected products were obtained in reduced yield. However, the desired products were obtained in good yield at moderate temperature In addition, mechanistic studies revealed that the synthetic route involved iron-based subsequent reactions of addition and removal of sulfur.
