In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Determination of cis-trans isomers of amine and pyridine platinum(II) complexes by J(Pt-H) coupling constants, published in 1990, which mentions a compound: 15227-42-6, Name is cis-Dichlorobis(pyridine)platinum(II), Molecular C10H10Cl2N2Pt, Recommanded Product: cis-Dichlorobis(pyridine)platinum(II).
The coupling constants 3J(Pt-H) of Pt(Xpy)2Z2 and Pt(Xpy)(DMSO)I2 (Xpy = py and its 4-Me, 3,5-Me, 4-Cl, 4-CN, 4-HOCH2, 4-AcO derivatives; Z = Cl, I, Br, ONO2) were recorded. The 3J(Pt-H) values of the cis complexes are 42 ± 2 Hz, while those of the trans derivatives are 31.5 ± 2.5 Hz. 2J(Pt-H) of [Pt(XNH2)2Z2] (X = Me, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl; Z = Cl, I, ONO2) were recorded. The 2J(Pt-H) values of the cis complexes are 66.5 ± 1.5z, those of the trans derivatives are 58 ± 2 Hz. Measurements of Pt-H coupling constants is a rapid method of identifying the cis and the trans isomers of Pt(II) complexes.
After consulting a lot of data, we found that this compound(15227-42-6)Recommanded Product: cis-Dichlorobis(pyridine)platinum(II) can be used in many types of reactions. And in most cases, this compound has more advantages.
