摘　　要：萘锂用于二苯乙炔的还原时,依据二苯乙炔与萘锂的摩尔比,可产生1,2-二锂-1,2-二苯乙烯(1)和1,4-二锂-1,2,3,4-四苯基-1,3-丁二烯(2)两种反应中间体。通过选择不同的亲电试剂与相应的中间体反应,合成了一系列包括2,3,4,5-四苯基硅杂环戊二烯衍生物、多芳基取代乙烯/二烯类衍生物,以及含氟芳香并苯类化合物等的π-电子体系化合物。对所得的各新化合物进行了详细表征,并测定了部分化合物的单晶结构。The reduction of diphenylacetylene with lithium naphthalenide produces two kinds of intermediates, 1 ,2-dilithio-1,2-diphenylethene （ 1 ） or 1,4-dilithio-1 ,2,3,4-tetrapheny1-1 ,3-butadiene （2） , depending on the ratio of diphenylacetylene to lithium naphthalenide. A series of π-electron systems＇ compounds, including 2,3,4,5- tetraphenyl silole derivatives, polyaryl substituted ethylene/diene derivatives, and partially fluorinated aromatic acenes were synthesized by reaction of various electrophiles with the corresponding intermediates, 1 or 2, produced in situ. All these new compounds were characterized, and the single crystal structures of the most of them were determined.
