A N-iodosuccinimide (NIS) -promoted [3+2] annulation reaction of aryldiazonium salts ArN2BF4 (Ar = 4-chlorophenyl, naphthalen-2-y, 3-methoxyphenyl, etc.) with guanidines RNHC(=NHHCl)NH2 (R = H, Me, Boc, 4-cyanophenyl, etc.) has been developed for the construction of previously elusive 2-aryl-5-amino-2H-tetrazoles I. This transformation takes advantage of readily available starting materials, proceeds under metal-free, mild and robust conditions, and holds broad functional group compatibility. The utility of this protocol is further manifested via coupling, annulation, deamination, and denitrogenation derivatizations. In the experiment, the researchers used many compounds, for example, 2,5-Dimethoxytetrahydrofuran(cas: 696-59-3Related Products of 696-59-3)
2,5-Dimethoxytetrahydrofuran(cas: 696-59-3) is a member of ether. When aromatic ethers are exposed to halogen in the presence or absence of a catalyst, they undergo halogenation, such as bromination.Related Products of 696-59-3
