An Overview of Synthetic Applications of s-Trichlorotriazine

Abstract

Organic synthesis often relies on readily available and versatile scaffolds that can be efficiently modified into diverse functional molecules. In many cases, reactions that are difficult to perform under conventional conditions can be successfully achieved using suitable catalysts. In recent years, organic catalysis has gained increasing attention because it frequently offers milder conditions, improved selectivity, and environmentally safer alternatives compared to traditional reagent-based methods. Among the various reagents explored for this purpose, s-trichlorotriazine (TCT), also known as cyanuric chloride, has emerged as an inexpensive and highly effective scaffold in synthetic chemistry. Due to its remarkable chemoselectivity, operational simplicity, and reduced formation of toxic by-products, TCT has been widely applied in numerous organic transformations. This review summarizes the reported literature on the synthetic applications of s-trichlorotriazine, highlighting its importance as both a catalyst and a reagent in modern organic synthesis.
