WebbThe copper-catalyzed cycloaddition of alkynes and azides (CuAAC) to give the corresponding 1,4-disubstituted-1,2,3-triazoles is the most successful and leading reaction within the click chemistry regime. Its heterogenization stands out as the innovative strategy to solve its environmental concerns and toxicity issue. In this report, magnetically … WebbThe three isomers of pentyne are pent-1-yne, pent-2-yne, and 3-Methylbut-1-yne. Among these three, pent-1-yne and pent-2-yne will exhibit position isomerism; pent-2-yne and 3-Methylbut-1-yne will exhibit chain isomerism; pent-1-yne and 3-Methylbut-1-yne will exhibit chain isomerism.
