(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.
