含官能团的间 -三苯基苯是一类构筑树型大分子、大环及多环大分子的功能模块 [1]。我们在环形聚苯大分子合成研究的工作中 ,需要多种对称及非对称 1 ,3 ,5 -三取代三苯基苯衍生物为构筑模块 ,前一类可采用取代苯乙酮在强酸 [2 ]催化下经三分子缩合直接合成得到 ,后一类主要通过 Inter-triphenyl benzene with functional groups is a kind of functional modules to construct the macromolecules, macrocycles and polycyclic macromolecules [1]. We need a variety of symmetrical and asymmetric 1,3,5 - trisubstituted benzene derivatives in the work of the research on the synthesis of ring polystyrene, which can be used to construct the module, the former one can be used to replace the acetophenone in the strong acid [ 2] catalyzed by the three-molecule condensation directly obtained, the latter mainly through
