Safety of Potassiumtris(1-pyrazolyl)borohydride. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Potassiumtris(1-pyrazolyl)borohydride, is researched, Molecular C9H10BKN6, CAS is 18583-60-3, about Synthesis and Reactivity of Neutral and Cationic Ruthenium(II) Tris(pyrazolyl)borate Alkylidenes. Author is Sanford, Melanie S.; Henling, Lawrence M.; Grubbs, Robert H..
A series of neutral and cationic ruthenium(II) alkylidenes containing the hydrotris(pyrazolyl)borate (Tp) ligand have been prepared The complex Tp(PCy3)(Cl)Ru:CHPh (2) was obtained by the reaction of (PCy3)2(Cl)2Ru:CHPh with KTp. Treatment of 2 with AgBF4 or AgSbF6 in the presence of a variety of coordinating solvents afforded [Tp(PCy3)(L)Ru:CHPh]+ (L = H2O, CH3CN, pyridine) in high yield. The dynamic NMR behavior of these new complexes is discussed, and the x-ray crystal structure of [Tp(PCy3)(H2O)Ru:CHPh]BF4 (3) is reported. Alkylidenes 2-5 alone do not catalyze olefin metathesis reactions. However, complex 2 is activated for ring-closing metathesis by the addition of HCl, CuCl, and AlCl3.
In some applications, this compound(18583-60-3)Safety of Potassiumtris(1-pyrazolyl)borohydride is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
