  描述：

  2-[4,5-Bis(diethoxymethyl)-1,3-dithiol-2-ylidene]-4,5-bis(diethoxymethyl)-1,3-dithiole 在 sodium tetrahydroborate 、 甲酸 作用下， 以 四氢呋喃 、 甲醇 、 二氯甲烷 为溶剂， 反应 2.0h， 生成 3,4,3',4'-tetrakis(hydroxymethyl)tetrathiafulvalene
  参考文献：
  名称：

  Tetraformyltetrathiafulvalene (TFTTF) and acetals, precursors of polyfunctionalized TTFs.

  摘要：

  A short synthesis of 1,3-dithiol-2-thiones bearing two aldehyde functionalities, free and/or masked as diethylacetals is described. They are shown to be convenient precursors for synthesizing di- and tetraformyl-TTF. When submitted to four-fold nucleophilic attacks, the latter readily affords new substituted derivatives such as the bis-(pyridazino)-TTF 8, the tetrakis-(hydroxymethyl)-TTF 9 and the tetravinylic-TTF 10 whose pi-donor ability has been characterized.
