The alkenes, cis-butene, C 12H 8 (acenaphthylene), and dienes, 1,3-butadiene and cyclopentadiene, were found to add to the mixed-metal disulfido complex CpMoMn(CO) 5(μ-S 2), 1, in the presence of irradiation by visible light to yield the new compounds CpMoMn(CO) 5[μS 2CH(CH 3)CH(CH 3)], 2, CpMoMn(CO) 5(μ-S 2H 3), 3, CpMoMn(CO) 5[μ-S 2CH 2CH(CH=CH 2)], 4, and CpMoMn(CO) 5(μ-S 2C 5H 6), 5, by 1,2-insertion of a C-C double bond into the S-S bond of 1. The cis-butene was inserted into the S-S bond with retention of stereochemistry. The reaction of 1 with C 60 yielded the complex CpMoMn(CO) 5(μ-S 2C 60), 6, in the presence of room light. A crystallographic study of 6 showed that the C 60 was inserted into the S-S bond at one of its 6,6 ring junctions. The reaction of 1 with elemental sulfur yielded the tetrasulfido complex CpMoMn(CO) 5(μ-S 4), 7, by addition of an S 2 group to the disulfido ligand. All new complexes were characterized by single-crystal X-ray diffraction analysis.
