2,3-二甲氧羰基-6,7-二氰基四硫富瓦烯衍生物合成

Synthesis of dimethyl 2-(4,5-dicyano-1,3-dithiol-2-ylidene)-1,3-dithiole-4,5-dicarboxylate

在亚磷酸三乙酯存在下,利用高度稀释技术,通过4,5-二氰基-1,3-二硫杂环戊烯-2-酮和4,5-二甲氧羰基-1,3-二硫环戊烯-2-硫酮的交叉偶联反应,成功地合成了关键前躯体二氰基四硫富瓦烯衍生物,用NMR、TOF-Ms和IR表征了其结构,并用循环伏安法和紫外吸收光谱初步评价了四硫富瓦烯衍生物的电化学性质和光物理性质。

With high dilution technique, cross-coupling reaction happens between 4,5-dicyano-1,3- dithiol-2-one（2） and dimethyl 2-thioxo-l,3-dithiole-4,5-dicarboxylate（3） in toluene to produce the asymmetrical diycano tetrathiafolvalene derivative （1） in the presence of triethyl phosphate. The structures are characterized by NMR, TOF-Ms and IR. Electrochemical and photo physical properties are evaluated with cyclic voltammograms and UV absorption spectrum.
