  CO₂ Capture by Multivalent Amino-Functionalized Calix[4]arenes: Self-Assembly, Absorption, and QCM Detection Studies

  摘要：

  The reactivity of CO2 with polyamino substrates based on calix[4]arenes and on a difunctional, noncyclic model has been studied. All the compounds react with CO2 in chloroform to form ammonium carb innate salts. However, the number, topology, and conformational features of the amino-functionalized arms present on the multivalent scaffold have a remarkable influence on the reaction efficiency and on the product composition. Tetraaminocalix[4]arenes 1-3 rapidly and efficiently react with 2 equiv of CO2, yielding highly stable hydrogen-bonded dimers formed by the self-assembly of two bis-ammonium bis-carbamate intramolecular salts. 1,3-Diaminocalix[4]arene 4 absorbs 1 mol of CO2, affording less stable zwitterionic ammonium carbamates. Gemini compound 5 reacts with CO2 in a 1:1 stoichiometry, forming hydrogen. bonded dimers of ammonium carbamate derivatives of moderate stability. For upper rim 1,3-diaminocalix[4]arene 6, in addition to the labile intramolecular salt, the presence of a self-assembled polymer was also detected. These systems were fully characterized in solution by H-1 and C-13 NMR spectroscopy, whereas the corresponding gas-solid reactions were further investigated by QCM measurements. Interestingly, the high affinity and reversibility of CO2 uptake shown by 1,3-diamino calix[4]arene 4 enabled us to attain a promising QCM device for carbon dioxide sensing.

Here, we describe our detailed efforts in developing a rhodium-catalyzed hydrogenolysis of unstrained C(aryl)–C(alkyl) bonds in 2,2′-methylenediphenols aided by removable directing groups. Good yields of the monophenol products are obtained with tolerating a wide range of functional groups. In addition, the reaction is scalable, and

  The reductive coupling of a chelated diimine ligand, Me2C(CH=NCH2(2-py))(2) (dmp(PM)(2)), by (TMEDA) TiCl2 afforded a Ti(IV) species containing a cyclopropane ring, (Me2Pr)-Pr-c(cis-2,3-NCH2(2-PY))(2)TiCl2 (1). Dimeric [(Me2C(CH2N=CH(2-py)(CH2(mu-N)CH2(2-Py))Mg](2) (3) was generated in the magnesium reduction of Me2C(CH2N=CH(2-py))(2) (dmp(PI)(2)) as its reduction incurred HAT. A di-azaallyl precursor was used to generate 7-membered ring chelates [DBM(PI-)(PI2-)Cr-III](2) (4) and [DBM(PI)(PI')}Fe](2) (5). Structural studies of 1, 3 and 4 are included, as are electronic assessments of the reductive coupling to afford 1, and the paramagnetism of 3. (C) 2018 Elsevier Ltd. All rights reserved.
