The thermal reaction of dicarbonyl-η5-cyclopentadienyl(2-thienoyl)iron with a series of substituted acetylenes to give indenones and cyclopentathiophenones have been reinvestigated.The results obtained support a reaction mechanism involving initial acetylene insertion followed by that of carbon monoxide, in contradiction to the previously reported results.The reaction products were identified and characterized primarily using 2D 1H nmr spectroscopy.
