A simple Palladium catalyst system for the efficient cyclotrimerization of acetylenes


Abstract


A cyclotrimerization of 4-R-phenylacetylenes variously substituted is performed using Pd(OAc)2 and Ph3P as catalytic system. The substituted 1,3,5-triphenylbenzenes and 1,2,4-triphenylbenzenes iso-lated were characterized by NMR spectroscopy and a reaction mechanism is also proposed.
