Greener synthesis of 1,2,3-triazoles using a copper(i)-exchanged magnetically recoverable β-zeolite as catalyst

Abstract

Herein, we describe the preparation and thorough characterization of a novel magnetically recoverable copper(I)-exchanged β-zeolite and its use as an efficient catalyst for the synthesis of 1,2,3-triazoles via the one-pot...

Development of a Novel Three‐step Sonogashira Cross Coupling/Deacetonation/Cycloaddition Protocol for the Synthesis of 4‐aryl‐1,2,3‐triazoles Using 2‐methyl‐3‐butyn‐2‐ol as a Versatile Acetylene Surrogate

“…Interestingly, when THF was used as solvent, the product was also obtained, albeit in moderate yield (entry 7). Taking into account that the development of more sustainable methods is one of our prime concerns, [7b,9g,15] we have studied the use of 2‐MeTHF, a biobased solvent, as it can be produced from renewable resources. To our delight when we performed the reaction in 2‐MeTHF, product 4 was obtained in 82% yield (entry 8).…”
