Palladium(II) octaalkoxy- and octaphenoxyphthalocyanines: Synthesis and evaluation as catalysts in the Sonogashira reaction

Octaalkoxy- and octaphenoxysubstituted palladium phthalocyanines were used as a new family members of cross-coupling catalysts in the Sonogashira reaction. For the first time it was shown that terminal alkynes reacted mildly with p-substituted aryl bromides in gently conditions at room temperature under Pd and Cu-cocatalysis to give the corresponding phenylacetylenes. This protocol represents the use of palladium phthalocyanines as homogeneous catalysts in the Pd/Cu-promoted Sonogashira reaction.
