1,2,4-Triazoles

Abstract The research field of 1,2,4-triazoles has been covered from 2007 until June 2019. In this period, a vast number of publications have appeared on the topic. An attempt was made to review the most important publications on the properties ( 2 Theoretical methods , 3 Experimental structural methods , 4 Thermodynamic aspects ), reactivity ( 5 Reactivity of fully conjugated rings , 6 Reactivity of non-conjugated rings , 7 Reactivity of substituents ), ring synthesis ( 8 Ring synthesis from acyclic compounds , 9 Ring synthesis by transformation of another ring ), and various applications ( Section 10 ) of this heterocycle. For a comprehensive view of the field, it is recommended to read this article together with the earlier articles published in CHECI (1984), CHEC-II (1996) and CHEC-III (2008).
