资源简介：
Selective and efficient preparation of a new type of nitrogen-containing 15-membered
triacetylenic macrocycles named 1,6,11-tris(arylsulfonyl)-1,6,11-triazacyclopentadeca-3,8,13-triynes (1) (Ar1 = Ar2 = Ar3 = 4-methylphenyl, 1aaa; Ar1 = Ar2 = 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 2,5,8-tris[(4-methlphenyl)sulfonyl]-2,5,8-triazatrindane, 11aaa,
when treated with Pd(PPh3)4 in refluxing toluene.
