Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 62-23-7, Name is 4-Nitrobenzoic acid, molecular formula is , belongs to phthalazine compound. In a document, author is Raghavendra, G. Jeevan, Recommanded Product: 4-Nitrobenzoic acid.
One-Pot Four Component Synthesis of 3-Amino-1-(1H-indol-2-yl)-5,10-dioxo-5,10-dihydro-1H-pyrazolo[1,2-b]phthalazine Derivatives Mediated by [DBUH][OAc]
One-pot, four component, green, and efficient synthesis of 3-amino-1-(5-nitro-1H-indol-2-yl)-5,10-dioxo-5,10-dihydro-1H-pyrazolo[1,2-b]phthalazine derivatives by reaction of phthalic anhydride with hydrazine hydrate, 5-nitro-1H-indole-3-carboxaldehyde-indole-3-carboxaldehydes and malononitrile-ethyl cyanoacetate in the presence of [DBUH][OAc] at 60-65 degrees C is developed. The method is characterized by short reaction time, high yields, and purity of products formed.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 62-23-7, in my other articles.
