摘要：

An inexpensive, simple, and greener catalytic system with lower toxicity using CuFe2O4 nanoparticles in the presence of piperidine and dry toluene as a solvent has been reported for the synthesis of 1,4-diphenylbutadiyne-1,3, via C-H activated aerobic C-sp-C-sp homocoupling. This protocol provides 66 % of yield at the gram-scale level making it appropriate for production at a larger scale. The catalyst shows reusability for up to five cycles without losing any significant catalytic activity.
