, p. 796 - 802 (2011)
Novel copolyacrylates containing various molar ratios of 5,10,15-tri[p-(9-methoxy-triethylenoxy)phenyl]-20-(p-acryloxyphenyl)porphyrin units in the chains have been synthesized, and their chemical structure was determined by NMR and MALDI-TOF mass spectrometry. Sensing response of the synthesized copolymers has been tested for trifluoroacetic and hydrochloric acids and nitrogen dioxide analytes. The reported sensing data indicate that porphyrin units are interacting with analytes in a reversible fashion.
Preparation and characterization of technetium-99m complexes with new diphosphines containing polyether groups

We report the synthesis and characterization of three new diphosphine ligands with polyether groups of general formula R(OCH2CH 2)nPPhCH2CH2PPh(CH 2CH2O)nR: 1 (R = Me, n = 3), 2 (R = Bu, n = 3) and 3 (R = Bu, n = 4). trans-[99mTcO2L2] + complexes were prepared by reaction between the diphosphine ligands and the 99mTc-gluconate precursor. The homologous rhenium complexes, trans-[ReO2L2]Cl (L = 1,2,3), were synthesized by ligand substitution reaction with [ReO2py4]Cl and oxorhenium (V) gluconate, and characterized by IR, ESMS and 1H, 13C{ 1H}, 31P{1H} NMR spectroscopy. All these data are consistent with the formation of diphosphine complexes chelated to the trans-ReO2 unit. The HPLC analyses of rhenium and 99mTc complexes display very similar profiles and retention times, consistent with the formation of the homologous complexes. Preliminary biodistribution studies with rats show significant differences between the behaviour of the three 99mTc complexes. Copyright

In this study, the heterogeneously catalyzed alkoxycarbonylation of olefins with CO2based on a supported ionic-liquid-phase (SILP) strategy is reported for the first time. An [Ru]@SILP catalyst was accessed by immobilization of ruthenium complex on a SILP, wherein imidazolium chloride was chemically integrated at the surface or in the channels of the silica gel support. An active Ru site was generated through reacting Ru3(CO)12with the decorated imidazolium chloride in a proper microenvironment. Different IL films, by varying the functionality of the side chain at the imidazolium cation, were found to strongly affect the porosity, active Ru sites, and CO2adsorption capacity of [Ru]@SILP, thereby considerably influencing its catalytic performance. The optimized [Ru]@SILP-A-2 displayed enhanced catalytic performance and prominent substrate selectivity compared to an independent homogeneous system under identical conditions. These findings provide the basis for a novel design concept for achieving both efficient and stable catalysts in the coupling of CO2with olefins.

Ionic liquids with an ether-functionalised cation and the bis(2-ethylhexyl)phosphate anion show thermomorphic behaviour in water, with a lower critical solution temperature. These ionic liquids are useful for homogeneous liquid-liquid extraction of first-row (3d) transition metals.
