Abstract

A procedure for the formation of a nitrate-encapsulating tripalladium(II) cage self-assembly of Pd(NO) with 1,3-bis(dimethyl(pyridin-4-yl)silyl)propane (L) was developed. The self-assembly reaction initially produces spiro-type macrocycles, PdL, and finally results in transformation into a nitrate-encapsulated cage, [(NO)@PdL], in the mother liquor. The reaction of PdX (X = BF, ClO, PF, and CFSO instead of NO) with L gives rise to a spiro species, PdL, as the final product, and anion exchange of the spiro products, PdL, with NO produces the tripalladium cage [(NO)@PdL].

摘要

开发了一种用于形成硝酸盐包封的三钯（II）笼的方法，即钯（II）硝酸盐与1,3 - 双（二甲基（吡啶 - 4 - 基）甲硅烷基）丙烷（L）的自组装。自组装反应最初产生螺环型大环化合物PdL，最终在母液中转化为硝酸盐包封的笼状化合物[(NO)@PdL]。钯（II）卤化物（X = BF₄⁻、ClO₄⁻、PF₆⁻和CF₃SO₃⁻，而非NO₃⁻）与L的反应产生螺环物种PdL作为最终产物，螺环产物PdL与NO₃⁻进行阴离子交换生成三钯笼状化合物[(NO)@PdL]。
