Metallic samarium reacts directly with Cyclooctatetraene in the presence of diaryldisulfide to give cyclooctatetraenyl(thiolato)samarium(III) complexes, Sm(µ-SAr)(C8H8)(thf)n]2(thf = tetrahydrofuran)(1, Ar = C6H5, n= 2; 2, Ar = 2,4,6-Me3-C6H2, n= 2; 3, Ar = 2,4,6-(Pri)3-C6H2, n= 1), the structures of which are confirmed by single crystal X-ray analyses of 1 and 3, while Yb reacts with diphenyldisulfide in thf to afford [Yb(SPh)2(thf)]n.
在二芳基二硫化物存在下,金属钐直接与环辛四烯反应,生成环辛四烯基(硫醇盐)钐(III)配合物,即 Sm(µ-SAr)(C8H8)(thf)n]2(thf = 四氢呋喃)(1, Ar = C6H5, n= 2; 2, Ar = 2,4,6-Me3-C6H2, n= 2; 3, Ar = 2,4,6-(Pri)3-C6H2, n= 1),其结构通过单晶X射线分析得到确认的1和3,而镱在四氢呋喃中与二苯基二硫化物反应生成[Yb(SPh)2(thf)]n。
