Magnetically Recoverable Cu0/Fe3O4-Catalysed One-Pot Tandem Synthesis of Sulfur-Containing Triazoles from Alkynes and Azide: DMSO Acts as an Alkylating Agent

Abstract

An efficient one-pot tandem nano Cu0/Fe3O4-catalysed synthesis of sulfur-containing triazoles from alkynes and azide has been developed. In this newly developed method, the readily available TMS-azide and dimethyl sulfoxide act as nitrogen and sulfur sources, respectively. The catalyst was magnetically recovered and reused six times without any significant loss of activity. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
