Abstract

An unprecedented tellurabenziporphyrin containing C, N, and Te donor atoms was synthesized by condensing benzitripyrrane and tellurophene diol under acid catalyzed conditions. The tellurabenziporphyrin readily forms a Pd(II) complex when treated with PdCl in CHCl/CHCN. The crystal structures of tellurabenziporphyrin and its Pd(II) complex revealed that the benzene ring hinders the π-electron delocalization. An unusual five-membered ring formed inside the macrocycle due to the strong interaction between "Te" and "N" in the Pd(II) complex.

摘要

一种前所未有的含 C、N 和 Te 供体原子的 tellurabenziporphyrin 通过在酸催化条件下缩合苯并三吡咯烷和碲二酚二醇合成。当用 PdCl 在 CHCl/CHCN 处理时，tellurabenziporphyrin 很容易形成 Pd(II) 配合物。tellurabenziporphyrin 和其 Pd(II) 配合物的晶体结构表明苯环阻碍了π-电子离域。由于 Pd(II) 配合物中“Te”和“N”之间的强相互作用，在大环内形成了一个不寻常的五元环。
