Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. , Recommanded Product: 1878-68-8, 1878-68-8, Name is 4-Bromophenylacetic acid, molecular formula is C8H7BrO2, belongs to phthalazine compound. In a document, author is Azarifar, Davood, introduce the new discover.
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.
