  Nitric Oxide Release Mediated by Calix[4]hydroquinones

  摘要：

  Calix[4]monohydroquinone has been used as a supramolecular system for the generation of NO gas. In a one-electron reduction scheme involving NO+subset of calix[4]monohydroquinone complex, NO is released without the presence of an external reducing agent. Free calix[4]monoquinone, thus obtained, can be reused for a new NO-releasing cycle after NaBH4-reduction to calix[4]monohydroquinone.

  Synthesis and self-assembly of novel calix[4]arenocrowns: formation of calix[4]areno[2]catenanes

  摘要：

  A series of novel calix[4]arenocrowns la-c were efficiently synthesized by a one-pot reaction of calix[4]monohydroquinone diacetate 5 with ditosylate 6 and its analogues in the presence of sodium hydroxide. It was found that the calix[4]arenocrowns could form stable pseudorotaxane-type complexes 2a-c with paraquat, and further self-assemble into calix[4]areno[2]catenanes 3a-C with dicationic salt 8 and p-bis(bromomethyl)benzene.

• The <i>p</i>-Bromodienone Route to Nucleophilic Functionalization of Calixarene <i>Exo</i> Rim
  作者：Francesco Troisi、Teresa Pierro、Carmine Gaeta、Placido Neri

  DOI：10.1021/ol8027708

  日期：2009.2.5

  Easily accessible calixarene p-bromodienone derivatives undergo a silver-mediated nucleophilic substitution and a subsequent rearomatization with a range of different O-nucleophiles (alcohols and carboxylates) to give p-alkoxy- or p-acyloxycalixarenes in workable yields. This approach can be considered a general “p-bromodienone route” to functionalize calixarene exo rim with nucleophiles.

  The epoxidation of quinone rings of calixquinones represents a valid route for the introduction of oxygenated functionalities into the de-tert-butylated calixarene walls originating cis-diepoxy-p-dione moieties. Carbonyl reduction of these systems leads to hybrid calixarenes containing dianhydroinositol moieties (calixinositols) belonging to the calixcyclitols family. The regio- and stereochemistry

• Electrochemistry and ion-sensing properties of calix[4]arene derivatives
  作者：Shanshan Chen、Richard D. Webster、Carmen Talotta、Francesco Troisi、Carmine Gaeta、Placido Neri

  The cyclic voltammetric properties of several substituted calix[4]arenes were examined in acetonitrile and dichloromethane. The compounds that contained one phenolic group in the macrocyclic cavity were able to be electrochemically oxidised at positive potentials. In acetonitrile, cyclic voltammetry experiments indicated that the phenolic compounds were oxidised in a two-electron (one-proton) process over all measured scan rates (up to 50 Vs(-1)), while in dichloromethane, the oxidation process occurred by one-electron at scan rates >= 5 V s(-1), to most likely form the radical cations. In both solvents, longer timescale (minutes to hours) controlled potential coulometry experiments indicated that the oxidation process occurred by two-electrons per molecule, to form reactive diamagnetic cations that could not be reduced back to the starting materials under electrolysis conditions. The ion-sensing properties of the compounds were investigated in polymer membrane ion-selective electrodes and it was found that they responded reversibly in a Nernstian fashion to Groups 1 and 2 metals and had the highest selectivity to the cesium cation.
