m-Calix[3]amide having pyridine on the benzene ring (PyC3A) was synthesized by the cyclization of methyl 3-nonylamino-5-(pyridin-4-yl)benzoate using lithium 1,1,1,3,3,3-hexamethyldisilazide (LiHMDS). The molecular cage 3Pd·2PyC3A was prepared from a 2:3 mixture of PyC3A and [Pd(dppp)(OTf)2] in CDCl3/CD3OD (5/1 in volume). On the other hand, in CDCl3, the formation of a polymeric mixture was confirmed.
通过使用 1,1,1,3,3,3-hexamethyldisilazide (LiHMDS) 环化 3-壬基氨基-5-(吡啶-4-基)苯甲酸甲酯,合成了苯环上有吡啶的间萼[3]酰胺(PyC3A)。分子笼 3Pd-2PyC3A 由 PyC3A 和 [Pd(dppp)(OTf)2] 的 2:3 混合物在 CDCl3/CD3OD (体积比为 5/1)中制备而成。另一方面,在 CDCl3 中,确认了聚合物混合物的形成。
