dimesitylgermanedithiolate reacted with titanocene or zirconocene dichloride to give 2,2-dimesityl-1,3-dithia-2-germa-4-titanacycle (3a) and its zirconocene analogue (3b), which afforded a stable 2,3,4,5-tetrathiagermolane (4) in treatment with S2Cl2. The reaction of 3b with Ph2GeCl2 gave unsymmetric 1,3,2,4-dithiadigermetane (5). The bis(η5-cyclopentadienyl) derivative of cis-2,3-di-t-butyl-2,3-diphenyl-1
二甲苯基锗二硫醇锂与二茂钛或二氯化锆反应生成 2,2-dimesityl-1,3-dithia-2-germa-4-titanacycle (3a) 及其二茂锆类似物 (3b),得到稳定的 2,3,4,用 S2Cl2 处理的 5-tetrathiagermolane (4)。3b 与 Ph2GeCl2 的反应得到不对称的 1,3,2,4-二硫二锗烷 (5)。从锂1获得的顺式-2,3-二-叔丁基-2,3-二苯基-1,4-二硫杂-2,3-二硅-5-钛环戊烷(7a)的双(η5-环戊二烯基)衍生物, 2-二叔丁基-1,2-二苯基乙硅烷-1,2-dithiolate 与亲电试剂(SCl2、S2Cl2、Se2Cl2、R2GeCl2)反应得到相应的杂环。
