prepared either by ligand transfer to [Cl2M(tpbz)] from (R2C2S2)SnR′2 (R = CN, R′ = Me; R = Me, R′ = nBu) or by a direct reaction between tpbz and [M(S2C2R2)2] (M = Ni, Pd, Pt; R = Ph, p-anisyl) in a 1:1 ratio. The formation of dimetallic [(R2C2S2)M(tpbz)M(S2C2R2)] attends these syntheses in modest amounts, but the open-ended compounds are readily separated by silica chromatography. As affirmed by X-ray
通过从 (R 2 C 2 S 2 )SnR将配体转移到 [Cl 2 M(tpbz)] 来制备具有 1,2,4,5-四(二苯基膦基)苯 (tpbz) 的开放式单金属化二硫烯配合物' 2 (R = CN, R' = Me; R = Me, R' = n Bu) 或通过 tpbz 和 [M(S 2 C 2 R 2 ) 2 ] (M = Ni, Pd, Pt ;R = Ph, p-茴香基),比例为 1:1。双金属[(R 2 C 2 S 2 )M(tpbz)M(S 2 C 2 R 2)] 以适度的量参与这些合成,但开放式化合物很容易通过硅胶色谱法分离。正如该组众多成员的 X 射线晶体学表征所证实的那样,[(R 2 C 2 S 2 )M(tpbz)] 化合物在其完全还原的 ene-1,2-dithiolate 形式中显示出二硫烯配体与二价基团连接10个离子。从[(Ph 2 C 2 S 2 )Pt II
