, p. 11558 - 11560 (2012)
The synthesis, structural and gas sorption studies of a porous Cu(ii) coordination polymer featuring 1H-indazole-5-carboxylic acid (H2L) are presented. [Cu(HL)2] is a thermally and hydrolytically robust 4-connected 3D coordination polymer of NbO topology and is replete with 1D channels that permit selective and hysteretic sorption of CO2.

Paragraph 0070-0073, (2021/06/26)
The invention relates to an electric reduction preparation method of aminobenzoic acid represented by formula I and ester thereof. The preparation reaction of the method is shown in the description; and in the reaction formula, R is selected from hydrogen, a methyl group, an ethyl group, a benzyl group, a C3 or C4 straight-chain alkyl or branched-chain alkyl group, -NO2 is selected from 4-NO2 or 5-NO2, and Y is selected from H or 4-NHCOC3H7-n. The electroreduction preparation method of aminobenzoic acid and ester I thereof is characterized in that in a separated electrolytic cell, an acidic solution of nthe itrobenzoic acid and ester III thereof is taken as a catholyte; the voltage of a cathode working electrode relative to a reference electrode is 1.00-2.50 V; and an anolyte is an acidicsolution, the current density is 25.0-250.0 mA/cm, and the electrolysis temperature is 15-90 DEG C.
Gas-liquid flow hydrogenation of nitroarenes: Efficient access to a pharmaceutically relevant pyrrolobenzo[1,4]diazepine scaffold

Using a Tube-in-Tube device based on the amorphous Teflon AF-2400 fluoropolymer, a series of nitroarenes was hydrogenated to afford the corresponding aniline compounds. The system was then applied to the construction of a pyrrolobenzo[1,4]diazapene scaffold through a tandem hydrogenation-condensation-hydrogenation sequence.
One-dimensional channels encapsulated in supramolecular networks constructed of zinc(II), manganese(II), or nickel(II) atoms with 3-(Carboxymethyl)-2, 7-dimethyl-3H-benzo[d]imidazole-5-carboxylic Acid

Four complexes with supramolecular architectures, namely, MZCA·3H2O (1), [Zn(H2O)6] 2+·[MZCA]2·[H2O]6 (2), [Mn(MZCA)2(H2O)4]·2H2O (3), and [Ni(MZCA)2(H2O)4]·2H2O (4) [MZCA = 3-(carboxymethyl)-2, 7-dimethyl-3H-benzo[d]imidazole-5-carboxylic acid], were synthesized and characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. Complexes 1 and 2 display a remarkable 3D network with 1D hydrophilic channels. Complexes 3 and 4 are isostructural and exhibit a 3D structure encapsulating 1D 24-membered ring microporous channels. The UV/Vis and fluorescent spectra were measured to characterize complexes 1-4. The thermal stability of complexes 2-4 were also examined.
