Piperazines were originally named because of their chemical similarity with piperidine, part of the structure of piperine in the black pepper plant (Piper nigrum). 103-76-4, formula is C6H14N2O, Name is N-(2-Hydroxyethyl)piperazine. The -az- infix added to “piperazine” refers to the extra nitrogen atom, compared to piperidine. It is important to note, however, that piperazines are not derived from plants in the Piper genus. Recommanded Product: N-(2-Hydroxyethyl)piperazine.
Ou Yang, Cheng-Hsin;Liu, Wan-Hsuan;Yang, Sheng;Chiang, Yao-Yu;Shie, Jiun-Jie research published 《 Copper-Mediated Synthesis of (E)-β-Aminoacrylonitriles from 1,2,3-Triazine and Secondary Amines》, the research content is summarized as follows. A simple protocol for the synthesis of (E)-β-aminoacrylonitriles RCH=CHCN (R = dimethylamino, piperidin-1-yl, imidazol-1-yl, etc.) via Cu(OAc)2-mediated nucleophilic addition of secondary amines such as piperidine, dimethylamine, imidazole, etc. to 1,2,3-triazine and an aerobic oxidation reaction was described. The reactions, which were studied with a broad substrate scope, are effective with cyclic, heterocyclic, aliphatic, allylic, and benzylic amines as well as L-proline derivatives The reactions use catalytic Cu(OAc)2 to promote 1,2,3-triazine addition with various secondary amines, followed by in situ loss of nitrogen and subsequent imine oxidation to generate the corresponding (E)-β-aminoacrylonitriles in good yields with excellent stereoselectivities. These copper(II)-mediated aerobic oxidation reactions proceed under mild reaction conditions by oxidation of the Cu(II) species using mol. oxygen to complete the cycle without the participation of ligand, base or chem. oxidant additives.
Recommanded Product: N-(2-Hydroxyethyl)piperazine, 1-(2-Hydroxyethyl)piperazine is a useful research compound. Its molecular formula is C6H14N2O and its molecular weight is 130.19 g/mol. The purity is usually 95%.
1-(2-Hydroxyethyl)piperazine is a chemical solvent that is used for the absorption of amines and other compounds. It has been shown to have a high affinity for acidic substances, which may be due to its ability to form hydrogen bonds with them. 1-(2-Hydroxyethyl)piperazine is also used in sample preparation for the analysis of amines and other compounds in fruit extracts. The solubility of 1-(2-Hydroxyethyl)piperazine depends on the experimental conditions, including pH, temperature, and pressure. FT-IR spectroscopy has been used to measure the vibrational modes of 1-(2-Hydroxyethyl)piperazine molecules. The IR spectrum revealed that this compound contains a hydroxyl group and two fatty acid chains with one or more hydroxyl groups at their terminal end. The nmr spectrum showed that 1-(2-Hydroxyethyl)piperazine contains an NH proton as well as, 103-76-4.
