  Synthesis of Ag⁺-Selective Dipalladium(II) Metallohost Based on O-Alkyloxime Bis(N₂SO) Ligands

  摘要：

  Novel bis(N2SO) ligands 2a (= H4L2a) and 2b (= H4L2b) comprising O-alkyloxime, thiophenol, and phenol moieties were synthesized. The complexation of H4L2a and H4L2b with palladium(II) acetate afforded the dinuclear metallohosts [L2aPd2] and [L2bPd2], which have a recognition site consisting of two sulfur and four oxygen donor atoms. The metallohost [L2bPd2] strongly binds Ag+ to give [(L2bPd2)2Ag]+, whereas no detectable interaction between [L2bPd2] and hard metal cations (Na+, Ca2+, Y3+, La3+, and Lu3+) was observed.

• Synthesis of acyclic tetrakis- and pentakis(N₂O₂) ligands for single-helical heterometallic complexes with a greater number of winding turns

  Acyclic oligooxime ligands (H8L4 and H10L5) that have four or five N2O2 coordinating moieties (salamo moieties) were synthesised in order to obtain single-helical metal complexes with a greater number of winding turns. When the complexation of the tetrakis (salamo) ligand H8L4 with zinc(II) took place, a complicated mixture of zinc(II) complexes was formed. However, the mixture was converted to a discrete pentanuclear complex in the presence of a guest ion with a suitable size (La3+, Ba2+), which was evidenced by the well-resolved sharp 1H NMR spectra and the mass spectra. Other ions with a smaller size (Lu3+, Ca2+) did not lead to such a discrete species. The 1H NMR spectral feature of the pentanuclear complex [L4Zn4La(OAc)3] is consistent with the single-helical structure in which the nth benzene ring approximately lies on the (n+3)th benzene ring.
