prepared by reduction of ReO4− with SnCl2 in strongly acidic solution and in the presence of aliphatic thioethers of the general formula RCH2CH2SCH2CH2SCH2CH2R′ (“S2”; R, R′ = H, Et; R = S—Bu, R′ = Et; R = O—Et, R′ = H; R, R′ = O—Et). Alternatively the compounds can be obtained by ligand exchange reactions starting from [ReOCl4]− in methanolic solution. A representative derived from 5,8-dithiadodecane
摘要在强酸溶液中,在通式RCH2CH2S的脂肪族硫醚存在下,通过用SnCl2还原ReO4-制备了双核氧(V)络合物[ReO(“ S2”)Cl2] 2O。 CH2CH2SCH2CH2R'(“ S2”; R,R'= H,Et; R = S-Bu,R'= Et; R = O-Et,R'= H; R,R'= O —等等)。或者,可以通过在甲醇溶液中从[ReOCl4]-开始的配体交换反应获得化合物。已经通过X射线衍射研究了衍生自5,8-二二十二烷(R,R'= Et)的代表。该络合物由两个独立的[ReO(“ S2”)Cl2]单元桥接,该单元由氧原子桥接。每个rh原子都集中在一个扭曲的八面体中,赤道面由S2Cl2供体组形成。单元中的硫和氯原子相对于桥连氧处于反位置。
