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. 36809-26-4, Name is (4-Bromophenyl)diphenylamine, molecular formula is , belongs to phthalazines compound.

Synthesis of novel spiro[chromeno[4 ‘,3 ‘:3,4]pyrazolo[1,2-b]phthalazine-7,3 ‘-indoline]-2 ‘,6,9,14-tetraone
Fe3O4@Cys-SO3H magnetic nanocatalyst has been used as an effective and reusable solid acid catalyst for the one pot synthesis of novel spiro[chromeno[4′,3′:3,4]pyrazolo[1,2-b]phthalazine-7,3′-indoline]-2’,6,9,14-tetraone via a three-component reaction of phthalhydrazide, 4-hydroxycoumarin and isatin derivatives. Easy separation of catalyst, good yields of reaction and synthesis of novel heterocyclic compound are some advantages of this procedure.
