Recent Progress in the Synthesis of N²-Substituted 1, 2, 3-Triazoles

Abstract

N-Substituted 1,2,3-triazole is an important structural unit in organic chemistry, and has widely utilized in organic synthesis, medicinal chemistry and material science. The chemistry of N 1 -substituted 1,2,3-triazoles has attracted much attention from organic chemists, while the synthesis and application of their N 2 -isomers have been far less explored. The recent progress on the research field of N 2 -alkyl, allyl, propargyl, vinyl, aryl substituted 1,2,3-triazoles since year 2000 is summarized, including some research of our group. The content is classified by different synthetic methods, such as selective functionalization of 1,2,3-triazoles and oxidative cyclization of bisarylhydrazones or azobenzenes.

Mechanical and Thermal Properties of Polyether Polytriazole Elastomers Formed by Click-Chemical Reaction Curing Glycidyl Azide Polymer

“…Exploring the universe is a human dream, and propellant is the power source of spacecraft. The binder is an important component of solid propellant, and attempts have been made to incorporate energetic components into the binder to impart energy to the binder while ensuring good mechanical properties to meet the higher requirements for binders [1][2][3][4][5][6][7][8].…”

“…Compared with a hydroxy and isocyanate curing system, the alkynyl azide curing system has no side effects, is not sensitive to moisture, has greater thermal stability, and good compatibility with high-energy components (e.g., ammonium dinitramide, hydrazinium nitroformate) which are helpful for the practical application of high-energy components.
