corresponding ferroceno[1′,2′;1″,2″]bis(1,3-dithiol-2-thione) derivatives. Mono t-butyl and unsubstituted analogs were prepared in a similar manner. The X-ray structural determination showed that these derivatives adopted the conformation in which the 1,3-dithiol-2-thione rings were heaped on top of each other. In the crystal of ferroceno[1′,2′;1″,2″]bis(1,3-dithiol-2-thione), the molecules packed so as to put
从相应的三硫杂[3]二茂铁杂环戊烯制备六硫杂[3.3]二茂铁roc烷的叔丁基和双(叔丁基)衍生物。前者是椅子-椅子和椅子-船的异构体的混合物,而后者仅存在椅子-船的异构体。六硫[3.3]二茂铁烯与LiAlH 4生成四硫醇,使其与1,1'-硫代羰基二咪唑反应,得到相应的二茂铁[1',2'; 1“,2”] bis(1,3-二硫醇-2-硫酮)衍生物。单Ť丁基和未取代的类似物以类似的方式制备。X射线结构测定表明,这些衍生物采用1,3-二硫醇-2-硫酮环彼此堆积的构象。在二茂铁[1',2'; 1“,2”]双(1,3-二硫醇-2-硫酮)的晶体中,分子堆积使得分子轴有序并相互重叠及以下。二茂铁[1',2'; 1'',2'']双(1,3-二硫醇-2-硫酮)衍生物的脱硫偶联未成功。
