Direct Synthesis of 4-Aryl-1,2,3-triazoles via I2-Promoted Cyclization under Metal- And Azide-Free Conditions

We herein report an iodine-mediated formal [2 + 2 + 1] cyclization of methyl ketones, p-toluenesulfonyl hydrazines, and 1-aminopyridinium iodide for preparation of 4-aryl-NH-1,2,3-triazoles under metal- and azide-free conditions. Notably, this is achieved

A green metal-free "one-pot" microwave assisted synthesis of 1,4-dihydrochromene triazoles

The synthesis of several 4-aryl-1,4-dihydrochromene-triazoles was achieved via a metal-free "one-pot"procedure using PEG400 as the sole solvent in an eco-friendly process. Using microwave irradiation, the triazole derivatives were obtained in good yields and short reaction times starting from readily accessible building blocks.

Iodine-Mediated Condensation–Cyclization of α-Azido Ketones with p-Toluenesulfonyl Hydrazide for Synthesis of 4-Aryl-NH-1,2,3-Triazoles

A molecular iodine mediated condensation–cyclization reaction for the synthesis of 4-aryl-NH-1,2,3-triazoles has been developed from readily available α-azido acetophenones and p-toluenesulfonyl hydrazide. This reaction provides a metal-free strategy for the sequential formation of C–N and N–N bonds in mild condition.
