摘　　要：以苯并-1,3-二硫杂环戊烯为原料,通过金属化反应以及锂化二硫杂环戊烯与氯代硅烷反应合成了系列2-硅烷基取代苯并-1,3-二硫杂环戊烯化合物.测定了化合物的氧化电位,发现硅的引入导致苯并-1,3-二硫杂环戊烯的氧化电位明显降低,给体的给电子能力增强.A series of 2-silyl-substituted 1,3-benzodithiole compounds were synthesized by metallation reaction and subsequent reaction between lithiated dithiole and chlorosilanes with 1,3-benzodithiole as the starting material.Oxidation potentials of the new compounds were determined.It was found that introduction of silicone led to decrease in the oxidation potential of 1,3-benzodithiole and enhancement of the donating ability of the donors.
