The synthesis of some new electron π-donors carrying four or two methoxy groups is described. The precursor 5,6-dimethoxy-5,6-dihydro[1,3]dithiolo[4,5-b] [1,4]dithiin- 2-thione was synthesized and by coupling reactions the symmetrical 5,6,5’,6’-tetramethoxy-5,6,5’,6’-tetrahydro- [2,2’]bi[[1,3]dithiolo[4,5-b][1,4]dithiinylidene] and unsymmetrical 5,6-dimethoxy-5,6,5’,6’-tetrahydro-[2,2’]bi[[1,3]- dithiolo[4
描述了一些带有四个或两个甲氧基的新电子 π 供体的合成。合成了前体 5,6-二甲氧基-5,6-二氢[1,3]二硫醇[4,5-b][1,4]二硫因-2-硫酮,并通过偶联反应生成了对称的 5,6,5' ,6'-四甲氧基-5,6,5',6'-四氢-[2,2']bi[[1,3]dithiolo[4,5-b][1,4]二亚硫基]和不对称的5, 6-二甲氧基-5,6,5',6'-四氢-[2,2']双[[1,3]-二硫醇[4,5-[1,4]二亚硫基], 2-(5,6 -二甲氧基-5,6-二氢-[1,3]二硫醇[4,5-b][1,4]二噻英-2-亚基)-5,6-二氢-[1,3]二硫醇[4,5] -b][1,4]-二恶英和(5,6-二甲氧基-5,6-二氢-[1,3]二硫醇[4,5-b][1,4]二噻英-2-亚基)-6 ,7-二氢-5H-[1,3]二硫并[4,5-b][1,4]二硫平供体被制备。它们已通过光谱
