A metal-free tandem construction of S-S and C-S bonds is an operationally simple method to access a wide range of benzyl disulfanylsulfone derivatives in high to excellent yields. Moreover, the robustness of this tandem transformation has been demonstrated by gram-scale reactions, and a plausible mechanism is also proposed.</p>

The unified CuAAC-thiolation provides a wide range of triazole-fused eight-membered heterocycles in good to high (51-94%) yields under mild reaction conditions. Moreover, a three-component reaction is also achieved involving O-/N-propargyl benzyl thiosulfonates, benzyl bromide, and sodium azide to deliver fused-triazoles in 61-74% yields. From a synthetic point of view, the present protocol has been demonstrated at gram-scale reactions. A plausible mechanism is also proposed based on experimental results and control experiments.10aEight-Membered Heterocycles10aFused-Triazoles10aInterrupted-Click Reaction10aThiolation10athiosulfonates1 aReddy, Raju, Jannapu1 aWaheed, Md1 aKumari, Arram, Haritha1 aKrishna, Gamidi, Rama  uhttps://library.ncl.res.in/content/interrupted-cuaac-thiolation-construction-123-triazole-fused-eight-membered-heterocycles-o-n
