ChemInform Abstract: 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

Copper‐catalyzed three‐component reaction of aromatic aldehydes (III) with dimedone (II) and phthalhydrazide (I) or urazole (V) under neat conditions provides title indazolophthalazines (IV) and triazoloindazoles (VI) in good yields.
