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. 1878-68-8, Name is 4-Bromophenylacetic acid, molecular formula is , belongs to phthalazines compound. In a document, author is Azarifar, Davood, HPLC of Formula: C8H7BrO2.
Tetrakis(acetonitrile)copper(I) Hexafluorophosphate as an Efficient Catalyst for the Synthesis of Triazolo[1,2-a]indazole-1,3,8-trione and 2H-indazolo[2,1-b]phthalazine-trione Derivatives
Tetrakis(acetonitrile) copper(I) hexafluorophosphate, [Cu(CH3CN)(4)]PF6, was explored as an efficient catalyst to promote the three-component reaction of aryl aldehydes, dimedone and urazole or phthalhydrazide to afford the corresponding triazolo[1,2-a]indazole-1,3,8-trione and 2H-indazolo[2,1-b]phthalazine-trione derivatives respectively in high yields. The reactions were conducted at 80-100 degrees C under solvent-free conditions. The catalyst was easily prepared from available and inexpensive materials and was quantitatively recovered from the reaction by simple filtration and reused for a number of cycles with almost consistent activity.
