Resumen

The cycloisomerization reaction of triacetylenic macrocycles 1 was carried out in molten n-Bu₄NBr using either the Wilkinson's catalyst RhCl(PPh₃)₃, or PdCl₂ leading to good yields of the corresponding cycloisomerized compounds. It was possible to recycle the catalytic system. When PdCl₂/TBAB was used, palladium nanoparticles were identified by means of transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX).
