CuO nanoparticle catalysed synthesis of 2H-indazoles under ligand free conditions

open access: yesRSC Adv., 2014
A CuO nano catalysed one-pot synthesis of 2H-indazoles has been devised from easily accessible starting materials viz. 2-bromobenzaldehydes, primary amines and sodium azide under ligand free conditions. The nano CuO catalyst played an important role during the formation of the intermolecular C–N bond followed by the intramolecular N–N bond, providing ...

2,2′-(Propane-1,3-diyl)bis(2H-indazole)

open access: yesActa Crystallographica Section E, 2011
The title molecule, C17H16N4, is a bis-indazole crystallized in the rare 2H-tautomeric form. Indazole heterocycles are connected by a propane C3 chain, and the molecule is placed on a general position, in contrast to the analogous compound with a central C2 ethane bridge, which was previously found to be placed on an inversion center in the same space ...
