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。 When lithium naphthalene is used for reduction of tolanylene, 1,2-dilithio-1,2-diphenylethylene (1) and 1,4-dilithium-1 , 2,3,4-tetraphenyl-1,3-butadiene (2) two kinds of reaction intermediates. By selecting different electrophiles and reacting with the corresponding intermediates, a series of compounds including 2,3,4,5-tetraphenylsilacyclopentadiene derivatives, polyaryl-substituted ethylene / diene derivatives , And π-electron system compounds such as fluorine-containing aromatic acene compounds. The new compounds obtained were characterized in detail and the single crystal structure of some compounds was determined.
