Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter.402-49-3, Name is 1-(Bromomethyl)-4-(trifluoromethyl)benzene, SMILES is FC(C1=CC=C(CBr)C=C1)(F)F, belongs to phthalazine compound. In a document, author is Naeimi, Hossein, introduce the new discover, Computed Properties of https://www.ambeed.com/products/402-49-3.html.
A Schiff base based on chitosan was synthesized through treatment of chitosan and p-dimethylaminobenzaldehyde in methanol solution. This biopolymeric Schiff base was used to prepare a new first row transition metal complex of Ni(II). The biopolymeric Schiff base and the synthesized tetra-coordinated complex were characterized using Fourier transform infrared, H-1 NMR and C-13 NMR techniques. Then, an efficient synthetic method for functionalized 1H-pyrazolo[1,2-b] phthalazine-5,10-diones was successfully developed using one-pot domino reaction of ninhydrin and malononitrile with 3-arylamino-5,5-dimethyl-2-cyclohexenones catalysed by the chitosan-based Schiff base complex of Ni(II) at room temperature. The advantages of this protocol are easy work-up, short reaction times and high yield of products and also the catalyst can be readily isolated from the reaction mixture and recycled without loss of catalytic activity.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
