Título: | Amine templated open-framework vanadium(III) phosphites with catalytic properties |
Autor: | Iglesias, Marta CSIC ORCID ; Rojo, Teófilo; Arriortua, María I. | Fecha de publicación: | 2013 | Editor: | Royal Society of Chemistry (UK) | Citación: | Dalton Transactions 42(13): 4500-4512 (2013) | Resumen: | Four novel amine templated open-framework vanadium(III) phosphites with the formula (C5N2H14)0.5[V(H2O)(HPO3)2], 1 (C5N2H14 = 2-methylpiperazinium), and (L)4−x(H3O)x[V9(H2O)6(HPO3)14−y(HPO4)y(H2PO3)3−z(H2PO4)z]·nH2O (2, L = cyclopentylammonium, x = 0, y = 3.5, z = 3, n = 0; 3, L = cyclohexylammonium, x = 1, y = 0, z = 0.6, n = 2.33; 4, L = cycloheptylammonium, x = 1, y = 0, z = 0, n = 2.33) were synthesized employing solvothermal reactions and characterized by single-crystal X-ray diffraction, ICP-AES and elemental analyses, thermogravimetric and thermodiffractometric analyses, and IR and UV/vis spectroscopy. Single-crystal data indicate that 1 crystallizes in the triclinic system, space group P, whereas 2, 3 and 4 crystallize in the hexagonal space group P63/m. Compound 1 has a two-dimensional motif with anionic sheets of [V(H2O)(HPO3)2]− formula, whose charge is compensated by the 2-methylpiperazinium cations embedded between the layers. In contrast, 2, 3 and 4 present a pillar-layer network giving rise to a three-dimensional framework containing intersecting 16-ring channels with the primary amine templates and the crystallization water molecules enclosed in them. 1, 2, 3 and 4 behave as heterogeneous catalysts for the selective oxidation of alkyl aryl sulfides, with tert-butylhydroperoxide (TBHP) as the oxidizing agent, being active, selective and recyclable for several successive cycles of reaction. | Versión del editor: | http://dx.doi.org/10.1039/C2DT32286B | URI: | http://hdl.handle.net/10261/93572 | DOI: | 10.1039/C2DT32286B | ISSN: | 1477-9226 | E-ISSN: | 1477-9234 |
