Carbonylative coupling reaction of aryl iodides with ferrocenylethyne catalyzed by PdCl2 was carried out using sodium dodecyl sulphonate (SDS) as surfactant and water as solvent. The reaction gave much better yields of aryl ferrocenylethynyl ketones, which proceeded for 6 h at room temperature under a balloon pressure of carbon monoxide with Et-3 N as base.
