The development of novel methods for the preparation of aminotetrazoles is of long-standing interest to chemists due to the great importance of these compounds in chemistry and biology. Here, we report an efficient method for the preparation of aminotetrazoles fromsecondaryamides by selective C–C bond cleavage. Compared with the conventional laborious and cumbersome approaches to aminotetrazoles
