Abstract

The asymmetric unit of the title compound, C19H16N2O5S, contains four independent mol­ecules (A, B, C and D), with two mol­ecules (B and D) displaying disorder in their methyl­sulfanyl groups [occupancy ratios of 0.797 (11):0.203 (11) and 0.85 (2):0.15 (2)]. The nitro groups are twisted slightly out of the planes of the 2-pyrroline rings to which they are bonded with dihedral angles of 10.17 (1), 8.01 (1), 9.44 (1) and 8.87 (1)° in mol­ecules A, B, C and D, respectively. The 2-pyrroline rings are almost orthogonal to the attached tolyl rings, forming dihedral angles of 73.44 (1), 81.21 (1), 88.18 (8) and 73.94 (1)° for mol­ecules A, B, C and D, respectively. A weak intra­molecular O—H⋯O inter­action is observed in mol­ecules B and C. The two hy­droxy groups in each mol­ecule are involved in inter­molecular O—H⋯O hydrogen bonding. In the crystal, mol­ecules are connected via O—H⋯O and C—H⋯O hydrogen bonds, forming a complex three-dimensional network.

Abstract

A new 2:1 co-crystal of piroxicam and gentisic acid [systematic name: 4-hy­droxy-1,1-dioxo-N-(pyridin-2-yl)-2H-1λ6,2-benzo­thia­zine-3-carboxamide-2-(4-oxido-1,1-dioxo-2H-1λ6,2-benzo­thia­zine-3-amido)­pyridin-1-ium-2,5-di­hydroxy­benzoic acid, 2C15H13N3O4S·C7H6O4] has been synthesized using a microfluidic platform and initially identified using Raman spectroscopy. In the co-crystal, one piroxicam mol­ecule is in its neutral form and an intra­molecular O—H⋯O hydrogen bond is observed. The other piroxicam mol­ecule is zwitterionic (proton transfer from the OH group to the pyridine N atom) and two intra­molecular N—H⋯O hydrogen bonds occur. The gentisic acid mol­ecule shows whole-mol­ecule disorder over two sets of sites in a 0.809 (2):0.191 (2) ratio. In the crystal, extensive hydrogen bonding between the components forms layers propagating in the ab plane.

Abstract

The selective oxidation of veratryl alcohol (VA), a model compound of lignin, with oxygen molecules to produce veratraldehyde (VAld) was studied over monometallic Au, Pd, and bimetallic Au:Pd nanoparticles supported on a Ce0.62Zr0.38O2 mixed oxide for the first time. These bimetallic Au-Pd catalysts with Au:Pd molar ratios from 0.4 to 4.3 were synthesized by the sol-immobilization method. Furthermore, all the catalysts were characterized by inductively coupled plasma-atomic emission spectroscopy (ICP-AES), N2 physisorption, X-ray photoelectron spectroscopy (XPS), scanning transmission electron microscopy-high angle annular dark field (STEM-HAADF) imaging, energy dispersive X-ray spectroscopy (EDXS), and temperature programmed reduction (TPR) techniques. A synergistic effect between gold and palladium was observed over all the bimetallic catalysts in a wide range of studied Au:Pd ratios. Remarkably, the optimum Au:Pd ratio for this reaction was 1.4 with a turnover frequency of almost six times larger than for the monometallic gold and palladium catalysts. Selectivity to veratraldehyde was higher than 99% for the monometallic Au, Pd, and all the bimetallic Au-Pd catalysts, and stayed constant during the reaction time.
