(Object) To provide a process for producing a high-purity tetrathiafulvalene derivative in a high yield, and novel tetrathiafulvalene derivatives and their precursors.
(Constitution) The process for production comprises selectively cleaving one of the two rings of 1,3,4,6-tetrathiapentalene-2,5-dione to produce 1,3-dithiol-2-one-4,5-dithiolate dianion, and after reacting it with a compound having a monovalent or divalent organic group, effecting coupling of two molecules thereof. Novel tetrathiafulvalene derivatives and their precursors are represented by formulae (1) to (6) described in the specification.
(目的)提供一种高产率生产高纯度四硫杂戊烯衍生物的工艺,以及新型四硫杂戊烯衍生物及其前体。
(Constitution) 该生产工艺包括选择性地裂解 1,3,4,6-四硫杂戊烯-2,5-二酮的两个环中的一个环,生成 1,3-二硫醇-2-酮-4,5-二硫酸盐二元离子,然后与具有一价或二价有机基团的化合物反应,使其两个分子偶联。本说明书中所述的式 (1) 至 (6) 代表新型四硫代富勒烯衍生物及其前体。
