CuCr۲O۴ nanoparticles as a new and efficient catalyst for the sonogashira coupling of triarylamines and arylacetylene by microwave irradiation

چکیده مقاله

Ethynyl linked aromatic amines are often applied as a significant part in electrophotography [1] and light-emitting devices [2]. Also these compounds are used in synthesis of natural products [3], polymers [4] and inmolecular wires [5]. Synthesis of ethynyl linked aromatic amines has been carried out by Sonogashira coupling [6] which is a palladium-copper catalyzed reaction of halides substituted triarylamines and aryl acetylenes. In this research we combined the advantages of microwave irradiation and nanotechnology to find the more convenient and efficient reaction of triarylamine substituted iodide and aryl acetylenes to produce ethynyl linked triarylamines.
