One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 56-95-1, Name is Chlorhexidine Diacetate, formurla is C26H38Cl2N10O4. In a document, author is Amirmahani, Najmeh, introducing its new discovery. Formula: C26H38Cl2N10O4.
[TBP](2)SO4 ionic liquid catalyst for 4MCR of pyridazinoindazole, indazolophthalazine and pyrazolophthalazine derivatives
Tetrabutyl phosphonium sulfate ([TBP](2)SO4), as novel room-temperature ionic liquid (RTIL), was synthesized by a simple cost-effective method, characterized by H-1, C-13, P-31 NMR and FT-IR spectrophotometry. The newly prepared catalyst was used as an efficient catalyst in some four multicomponent reactions (4MCRs) e. g., to synthesis pyridazino[1,2-a]indazole, indazolo[2,1-b]phthalazine and pyrazolo[1,2-b]phthalazine. This green method has several advantages such as short reaction time, using simple methods to prepare catalysts and products, easy operation and high efficiency of products. In addition, the catalyst can be easily recovered and reused several times with reduced average activity. Graphic abstract
