Computed Properties of C19H19N2NaO2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Sodium 4-butyl-3,5-dioxo-1,2-diphenylpyrazolidin-4-ide, is researched, Molecular C19H19N2NaO2, CAS is 129-18-0, about Synthesis of certain new 3,5-dioxopyrazolidines of pharmacological interest. Author is Abou-Gharbia, M.; El Zanfally, S.; Khalifa, M..
Pyrazolidinediones I [R = R1 = 5-nitro-2-pyridyl (Q), R2 = R3 = Et, Pr, Bu; R = Q, Ph, R1 = Ph, R2 = Q, R3 = Bu; R = Q, R1 = Ph, R2 = R3 = Et] were obtained in 60-73% yield by treating Na derivatives of appropriately substituted pyrazolidinediones with QCl.
