In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Boron-pyrazole chemistry. II. Poly(1-pyrazolyl)-borates, published in 1967, which mentions a compound: 18583-60-3, mainly applied to BORATE POLYPYRAZOLYL BORON PYRAZOLES; POLYPYRAZOLYL BORATE BORON PYRAZOLES; PYRAZOLYL BORATE DIHYDROBIS; BORATE PYRAZOLYL DIHYDROBIS; DIHYDROBIS PYRAZOLYL BORATE; PYRAZOLYL BORATE HYDROTRIS; BORATE PYRAZOLYL HYDROTRIS; TETRAKIS PYRAZOLYL BORATE; PYRAZOLYL BORATE TETRAKIS; UNINEGATIVE BIDENTATE LIGANDS; LIGANDS BIDENTATE UNINEGATIVE; UNINEGATIVE TRIDENTATE LIGANDS; TRIDENTATE LIGANDS UNINEGATIVE; LIGANDS TRIDENTATE UNINEGATIVE; BORON PYRAZOLES POLYPYRAZOLYL BORATE; HYDROTRIS PYRAZOLYL BORATE; PYRAZOLES BORON POLYPYRAZOLYL BORATE; BIDENTATE LIGANDS UNINEGATIVE; BORATE PYRAZOLYL TETRAKIS, Recommanded Product: 18583-60-3.
cf. preceding abstract Alkali metal dihydrobis(1-pyrazolyl)borates, hydrotris(1-pyrazolyl)borates, and tetrakis(1-pyrazolyl)borates have been prepared from alkali metal borohydrides and pyrazole. The first 2 are parent compounds, each representing a new class of chelating agents. Dihydrobis(1-pyrazolyl)borates are uninegative bidentate ligands and react with divalent transition metal ions forming square-planar or tetrahedral chelates, while hydrotris(1-pyrazolyl)borates are uninegative tridentates yielding octahedral coordination compounds A study of the solvent- and cation-dependence in the N.M.R. spectra of poly(1-pyrazolyl)borate ions permitted assignment of the 3-H and 5-H doublets. All alkali metal poly(1-pyrazolyl)borates (I, Z = metal or onium ion) can be converted to isolable free acids of moderate stability. The synthesis and properties of representative compounds are described. 27 references.
As far as I know, this compound(18583-60-3)Recommanded Product: 18583-60-3 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
