A new inorganic-organic hybrid compound [Cd(H2L)(H2O)], 1, {where, H2L2- = 4,4′-sulfonylbis(phenylene)bis(oxamate)} was prepared under solvothermal conditions. The compound has a three-dimensional structure. The compound exhibits strong luminescence behavior, and was used for the detection of chromate and dichromate anions in aqueous media at low concentrations The compound exhibited high selectivity and recyclability for the detection of low concentrations (ppm levels) of chromate and dichromate ions. Compound 1 also is an effective catalyst for the Knoevenagel condensation involving aromatic aldehyde and malononitrile under green solvent-free conditions with high yield and recyclability. The experimental part of the paper was very detailed, including the reaction process of Ethyl oxalyl monochloride(cas: 4755-77-5Recommanded Product: 4755-77-5)
Ethyl oxalyl monochloride(cas: 4755-77-5) belongs to acyl chlorides. Lacking the ability to form hydrogen bonds, acyl chlorides have lower boiling and melting points than similar carboxylic acids. For example, acetic acid boils at 118 °C, whereas acetyl chloride boils at 51 °C. Like most carbonyl compounds, infrared spectroscopy reveals a band near 1750 cm−1.Recommanded Product: 4755-77-5
