模拟实验表明 ,联苯是硫芴和氧芴的前身物质之一 .联苯具备了硫芴和氧芴的基本碳骨架 ,它的两个苯环做为吸电子基团相互影响对方使α位氢活化 ,电负性很强的硫或氧进攻这两个位 ,夺去氢变成H2 S和H2 O ,其他的硫原子或氧原子再进攻失去氢的α位就可以搭成一个桥从而把能够自由扭动的联苯分子变成一个稳定的硫芴或氧芴分子 .所以说硫芴和氧芴与芴之间没有确定的相关性 Simulation results show that biphenyl is one of the precursors of thiofluorene and fluorene.biphenyl has the basic carbon skeleton of fluorene and fluorene, the two benzene rings of which act as electron-withdrawing groups and influence each other to make α Hydrogen activation, electronegativity strong sulfur or oxygen attack these two bits, remove the hydrogen into H2S and H2O, other sulfur atoms or oxygen atoms and then attack the loss of a hydrogen position can be a bridge to The freely twisting of the biphenyl molecules into a stable sulfur fluorene or oxygen fluorene molecule.So fluorene and fluorene fluorene and therefore there is no definitive correlation between
