Abstract :
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).
