《New efficient tetraphenyl silylated poly(azomethine)s based on “”pincer-like”” bis(imino)pyridine iron(III) complexes as heterogeneous catalysts for CO2 conversion》 was written by Sobarzo, Patricio A.; Terraza, Claudio A.; Maya, Eva M.. HPLC of Formula: 1195-59-1 And the article was included in European Polymer Journal in 2020. The article conveys some information:
Aromatic poly(azomethine)s containing simultaneously for the 1st time both tetra-Ph silane moieties and pincers of bis(imino)pyridine were prepared, to provide these polymers with a robust structure and ability to anchor metals. The polymers were prepared from difunctional monomers which provide an special conformation yielding moderate surface areas (up to 60 m2/g). The insolubility and further incorporation of Fe to these polymers have generated a new set of heterogeneous catalysts with high metal content, high thermal stability and with excellent catalytic performance in the cycloaddition of CO2 to epoxides to form cyclic carbonates. Very small amounts of catalysts work efficiently, in the absence of solvent, at moderate CO2 pressures (3 bar) showing very high yields of epoxide conversion (up to 95%), 100% of selectivity to the corresponding cyclic carbonate in all cases and high turn-over numbers (up to 7000) being reused at least five times with no apparent loss in catalytic activity. The new catalysts are more efficient than a similar catalyst previously reported for this conversion and work in milder conditions. The results came from multiple reactions, including the reaction of 2,6-Pyridinedimethanol(cas: 1195-59-1HPLC of Formula: 1195-59-1)
2,6-Pyridinedimethanol(cas: 1195-59-1) belongs to pyridine. Pyridine derivatives lend themselves to many roles in the spirited field of supramolecular chemistry – whether as the ligand backbone of metal-organic polymers or presiding over the key electronic stations of nanodevices. In biochemistry, pyridine-containing cofactors are necessary nutrients on which our lives depend. HPLC of Formula: 1195-59-1
