Application of 4971-56-6, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.4971-56-6, Name is Furan-2,4(3H,5H)-dione, molecular formula is C4H4O3. In a article，once mentioned of 4971-56-6
An efficient in-situ reduction and cyclization reaction for the synthesis of pyrazolo[4,3-f]quinoline, pyrazolo[3,4-f]quinoline, and pyrazolo[3,2-f]quinoline derivatives directly form 5-nitroindazole, 6-nitroindazole and 5-nitroindole in the presence of SnCl2·2H2O was reported. Compared to traditional synthetic methods, this approach has the advantages of stable reagents, easy obtaining raw material, and high yields. In this research, SnCl2·2H2O is the efficient reducing agent for the in-situ reduction and cyclization reaction of nitro-compound. In addition, this process provided an alternative approach for the synthesis of target compounds.
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 4971-56-6
