The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Potassiumtris(1-pyrazolyl)borohydride, is researched, Molecular C9H10BKN6, CAS is 18583-60-3, about Structural characterization and variable temperature 1H NMR of monoporphyrinate samarium(III) and erbium(III) complexes, the main research direction is samarium erbium porphyrinate pyrazolylborate preparation NMR.Category: piperazines.
Two samarium(III) and erbium(III) monoporphyrinate complexes stabilized by anionic hydrotris(pyrazolyl)borate (TpH) were prepared and characterized by elemental anal., UV-visible, IR, and mass spectra. Structural anal. revealed that seven N atoms from porphyrin dianion and TpH- coordinated to the lanthanide ions. The 1H NMR spectra showed Sm3+ has a slight effect on proton chem. shifts, whereas Er3+ has a heavy effect that leads to the up-field and downfield shift of proton chem. shift. The variable temperature 1H NMR reveals that the chem. shifts of protons of all complexes are temperature-dependent.
The article 《Structural characterization and variable temperature 1H NMR of monoporphyrinate samarium(III) and erbium(III) complexes》 also mentions many details about this compound(18583-60-3)Category: piperazines, you can pay attention to it, because details determine success or failure
