  The invention is directed to novel heterofulvene geminal dithiolate compounds and their selenium and tellurium analogs having the general formula wherein X is selected from S, Se and Te. R is selected from hydrogen, alkyl, aryl, or together forming a ring of carbon or hetero atoms, cyano and dithiocarbonate groups and R1 is selected from alkali, alkaline earth and transition metals, quaternary ammonium, alkyl, acyl, cyclic and heterocyclic groups, or together forming a ring. The novel method of preparing these compounds involves the reaction of a cis-dicyanotetraheterofulvalene derivative with two equivalents of an organic sulfide, selenide or telluride compound, eventually followed by reacting the reaction product with two equivalents of an organic halogenide. The new compounds are key synthetic intermediates for the preparation of tetrathiafulvalene derivatives and tetraselenafulvalene derivatives which are useful in optical printing of conducting patterns, in electrochromic displays and in high resolution lithography.

  本发明涉及具有通式的新型杂富烯宝石级二硫酸盐化合物及其硒和碲类似物。 其中 X 选自 S、Se 和 Te。R 选自氢、烷基、芳基或由碳原子或杂原子、氰基和二硫代碳酸酯基团共同形成的环，R1 选自碱金属、碱土金属和过渡金属、季铵、烷基、酰基、环状基团和杂环基团或共同形成的环。 制备这些化合物的新方法是将顺式二氰基四杂环戊烯衍生物与两当量的有机硫化物、硒化物或碲化物反应，最后再将反应产物与两当量的有机卤化物反应。这些新化合物是制备四噻富戊二烯衍生物和四硒富戊二烯衍生物的关键合成中间体，可用于导电图案的光学印刷、电致变色显示和高分辨率光刻。
