A smalllibrary of simple 1,4-disubstituted 1,2,3-triazoles was prepared using a known one-pot procedure starting from organic halides and terminal alkynes. The compounds were then tested for their antibacterial activity against normal and resistant species of Staphylococcus aureus.
Immobilized copper(II) on nitrogen-rich polymer-entrapped Fe<sub>3</sub>O<sub>4</sub>nanoparticles: a highly loaded and magnetically recoverable catalyst for aqueous click chemistry
magnetic copper catalyst was prepared via anchoring of copper sulfate onto multi‐layered poly(2‐dimethylaminoethyl acrylamide)‐coated magnetic nanoparticles and was characterized using various techniques. The catalyst was found to be active, effective and selective for one‐pot three‐component reaction of alkyl halide, sodium azide and alkyne, known as copper‐catalyzed click synthesis of 1,2,3‐triazoles.
