Abstract: The photolytic reaction of (Z)-1-ferrocenyltelluro-1-ferrocenyl-4-ferrocenyl-1-buten-3-yne with iron pentacarbonyl in hexane gives the tellurium coordinated carbonyl vinylallyl dinuclear iron complex 1, tellurium coordinated vinylallyl trinuclear iron complex 2, a lactone fused ferracyclopentadiene complex 3, and a butterfly complex 4. On reaction with PPh3, 1 undergoes fragmentation to yield a cyclopentadienone (7) and the starting material (Z)-1-ferrocenyltelluro-1-ferrocenyl-4-ferrocenyl-1-buten-3-yne. In addition, reactions of the tellurium ene-yne ligand with [ M(CO)(5)(THF)] or [ M(CO)(6)] give the M(CO)(5) adducts 8-10. All compounds have been characterized by IR, H-1 NMR and C-13 NMR spectroscopy and structures of 1-4 and 7 have been established by single crystal X-ray diffraction.
