  Role of anagostic interactions in cycloplatination of telluroethers: Synthesis and structural characterization

  摘要：

  Reactions of K2PtCl4 with TeRR' gave complexes of composition [PtCl2(TeRR')(2)] (R/R' = Ph-2(1a), o-tol(2) (1b), Mes2(1c), Ph/Mes (1d), o-tol/Mes (1e)). The complex [PtCl2(TeMes(2))(2)] in refluxing THF afforded a mononuclear cyclometalated complex [PtCl{(CH2C6H2Me2-4,6)TeMes}(TeMes(2))] (2). It tends to remain in equilibrium with a binuclear derivative [Pt(mu-Cl){(CH2C6H2Me2-4,6)TeMes}12 (3) in CDCl3 solution. The complexes Id and le did not undergo cyclometalation reaction under similar reaction conditions. The 2 on treatment with PPh3 gave [PtCl{(CH2C6H2Me2-4,6)TeMes}(PPh3)] (4). All the complexes have been, 3113, 125-re, characterized by elemental analysis and NMR (H-1, P-31, Te-125, Pt-195) spectroscopy. Anagostic interactions have been recognised for facilitation of cyclometalation reactions. The molecular structures of trans[PtCl2(TeMes)(2)] trans-[PtCl2(PhTeMes)(2)] (1d), trans-[PtCl2(o-tolTeMes)(2)] (le), [PtCl{(CH2C6H2Me2-4,6)TeMes}(TeMes(2))] (2) and [PtCl{(CH2C6H2Me2-4,6)TeMes}(PPh3)] (4) have been established unambiguously by single crystal X-ray diffraction analyses.

  A general and efficient procedure has been developed for the synthesis of organochalcogenides (selenides and tellurides) by a simple reaction of organoboronic acids and dichalcogenides catalysed by CuFe2O4 nanoparticles in PEG-400 without any ligand. This protocol offers the scope for access to a wide spectrum of chalcogenides including diaryl, aryl–heteroaryl, aryl–styrenyl, aryl–alkenyl, aryl–allyl, aryl–alkyl and aryl–alkynyl versions. The catalyst is magnetically separable and recyclable eight times without any loss of appreciable catalytic activity. The products are obtained in high purities after evaporation of solvent followed by filtration column chromatography.

  开发了一种合成有机硫族化合物（硒化物和碲化物）的通用且高效的方法，该方法通过在PEG-400中无任何配体存在下，CuFe2O4纳米颗粒催化有机硼酸与二硫族化合物的简单反应实现。该方案适用于获得包括二芳基、芳基-杂芳基、芳基-苯乙烯基、芳基-烯基、芳基-烯丙基、芳基-烷基和芳基-炔基等多种硫族化合物。催化剂具有磁性可分离和可循环使用八次而不会显著损失催化活性。产品经过溶剂蒸发和过滤柱层析后可获得高纯度。

  arylboronic acids by using copper(I) thiophene-2-carboxylate (CuTC) under mild conditions. Although other studies have reported that highly polar solvents (such as DMSO) or bases are required, this reaction was completed by using CuTC and common solvents under neutral conditions at room temperature. This cross-coupling reaction was performed with diaryl ditellurides and arylboronic acids bearing various
