| Abstract: The in situ reaction of ［(μ-t-BuS)(μ-Se)Fe2(CO)6］［Et3NH］, generated from ［(μ-t-BuS)(μ-CO)Fe2(CO)6］［Et3NH］ and selenium powder, with benzyl bromide, methylene diiodide, o-, m- and p-bis (bromomethyl) benzene gave one butterfly single cluster (μ-t-BuS)(μ-PhCH2Se)Fe2(CO)6 (3a) and four double clusters ［(μ-t-BuS)Fe2(CO)6］2(μ-SeZSe-μ) (Z=CH2,o-, m-, p-CH2C6H4CH2) (4a-d), respectively. Similarly, reaction of ［(μ-PhSe)(μ-S)Fe2(CO)6］［Et3NH］, formed from ［(μ-PhSe)(μ-CO)Fe2(CO)6］［Et3NH］ and elemental sulfur, with p-bis (bromomethyl) benzene afforded a double cluster ［(μ-PhSe)Fe2(CO)6］2 ［μ-S-(p-CH2C6H4CH2)-S-μ］ (5a), whereas ［(μ-PhSe)(μ-Se)Fe2(CO)6］［Et3NH］, formed from ［(μ-PhSe)(μ-CO)Fe2(CO)6］［Et3NH］ and elemental selenium, reacted with p-bis (bromomethyl) benzene to yield a double cluster ［(μ-PhSe)Fe2(CO)6］2［μ-Se-(p-CH2C6H4CH2)-Se-μ］ (5b). These new clusters 3a, 4a-d and 5a,5b have been characterized by elemental analysis, IR and 1H NMR spectroscopy. |
