Description Photolytic reaction of internal acetylenes, RCa parts per thousand CR' (R = Ph, Fc and R' = Ca parts per thousand CPh, Ca parts per thousand CFc, CHO) with iron pentacarbonyl, in presence of CS2, in hexane yields a 3,5-dithiacyclopentene ligand system supported on a Fe-2(CO)(6) framework. On reaction with diacetylenes substituted cis- and trans-3,5-dithiacyclopentene ligand, formed by the coupling of two molecules of the diacetylenes are observed, while, with 3-ferrocenylpropynal, along with coupled 3-ferrocenylpropynal products, cis-3,5-dithiacyclopentene ligand, formed by the coupling of one 3-ferrocenylpropynal and one ferrocenylacetylene is also observed. All compounds have been characterized by IR, H-1 NMR and C-13 NMR spectroscopy, mass spectrometry, and structures of 4a and 4c have been established by single crystal X-ray diffraction technique. In addition, DFT computational analyses of compounds 4a and 4c have been investigated in order to understand the bonding in complexes 4a and 4c.
