摘要：The treatment of [Cp*Fe(mu-eta(2):eta(4)-bdt)FeCp*] (1, Cp* =eta(5)-C5Me5, bdt = benzene-1,2-dithiolate) with 1/4 equiv. of elemental sulfur (S-8) gave a dinuclear iron-sulfur cluster [Cp*Fe(mu-eta(2):eta(2)-bdt) (cis-mu-eta(1):eta(1)-S-2)FeCp*] (2), which contains a cis-1,2-disulfide ligand. When complex 2 further interacted with 1/8 equiv. of S-8, another sulfur atom inserted into an Fe-S bond to give a rare product [Cp*Fe(mu-S(C6H4S2))(cis-mu-eta(1):eta(1)-S-2)FeCp*] (3). Unexpectedly, a trans-1,2 disulfide-bridged diiron complex [{Cp*Fe(bdt)}(2)(trans mu-mu-eta(1):eta(1)-S-2)] (4) was isolated from the reaction of complex 1 with 1/2 equiv. of S-8, which represents a structural isomer of [2Fe-2S] ferredoxin- type clusters. In addition, cis-1,2-disulfide-bridged complex 3 can slowly convert into trans-1,2-disulfide-bridged complex 4 and the complex [Cp*Fe(mu-eta(2):eta(2)-S2)(cis-mu-eta(1):eta(1)-S-2)FeCp*] (5) by self-assembly reaction at ambient temperature, which is evidenced by time- dependent H-1 NMR spectroscopy.
