= 4-methylphenyl, Ar3 = ferrocenyl, 1aab) has been achieved. Macrocycle 1aaa forms a very stable complex with Pd0, being the first palladium(0) complex with a macrocyclic triyne. The three triple bonds in 1aaa are responsible for the complexation. The X-ray structures of both the ligand 1aaa and its Pd0 complex are presented. Furthermore, compound 1aaa undergoes cycloisomerization into the corresponding
选择性和高效制备新型的含氮15元三炔大环化合物,称为1,6,11-三(芳基磺酰基)-1,6,11-三氮杂环戊adeca-3,8,13-三炔(1)(Ar 1= Ar 2= Ar 3= 4-甲基苯基,1aaa; Ar 1= Ar 2= 4-甲基苯基,Ar 3=二茂铁基,1aab)已经得到。大环1aaa与Pd 0形成非常稳定的络合物,是第一个具有大环三炔的钯(0)络合物。1aaa中的三个三键负责络合。两种配体的X射线结构介绍了1aaa及其Pd 0配合物。此外,当在回流的甲苯中用Pd(PPh 3)4处理时,化合物1aaa经历环异构化成相应的2,5,8-三[(4-甲基苯基)磺酰基] -2,5,8-三氮杂rin烷11aaa。
