New Advances in Chemical Research in 2021. In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 57196-62-0, name is 6-Methoxy-1,2,3,4-tetrahydroisoquinoline hydrochloride, introducing its new discovery. Synthetic Route of 57196-62-0
Eight lanthanide-copper coordination polymers of linear rigid 4-(4-pyridyl)benzoate(L1) and isonicotinate(L2), [LnCuI(L1)2(OAc) (H2O)]n (Ln = Pr, 1; Nd, 2; Sm, 3; Eu, 4; Gd, 5), [Ln2Cu4I 3(L2)7 (H2O)]n (Ln = La, 6; Pr, 7), and [Nd2Cu7I6(L2) 7 (H2O)6]n·2.5nH2O (8), were hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction. The three-dimensional frameworks of 1-5 can be described as wave-like layer modules of [Ln(L1)2(OAc) (H2O)]n linking with each other through dimeric units of Cu2I2, whereas that of compounds 6 and 7 are constructed by layer modules of [Ln2(L2)7(H 2O)]nn- and Cu4I3 clusters. As for 8, dimeric units of Nd2(L2)7(H2O)6 connect layered polymeric [Cu7I6]nn+ forming a 3D framework.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 57196-62-0
