Preparation of 1,2-bis(pyrazol-1-yl)benzene: 'Modern' cross-coupling vs. the 'Classic' nucleophilic substitution approach
Ivashchuk, Olga,Sorokin, Vladimir I.
, p. 57 - 59 (2009)
Several potential methods for the preparation of 1,2-bis(pyrazol-1-yl) benzene, a prospective ligand for transitional metals, starting from 1,2-dihalobenzenes and pyrazole have been studied. Cross-couplings of 1,2-dichloro-, - dibromo- and -diiodobenzenes
Copper-catalyzed C-N bond formation with N-heterocycles and aryl halides
Boswell, Mikki G.,Yeung, Fanny G.,Wolf, Christian

The microwave-assisted, cuprous oxide catalyzed coupling of aryl bromides and iodides with imidazole, benzimidazole, pyrazole, or triazole was found to give a wide range of N-aryl heteroaromatic products in good to high yields. Aryl dibromides undergo sel
N-aryl pyrazoles: DFT calculations of CH acidity and deprotonative metallation using a combination of lithium and zinc amides

A series of N-aryl and N-heteroaryl pyrazoles have been deproto-metallated using a 2,2,6,6-tetramethylpiperidino-based mixed lithium-zinc combination. Mono-, di-, and tri-iodides have been obtained after subsequent trapping with iodine, depending on the s
Polykis(pyrazol-1-yl)benzenes: preparation, structure, and complexation with copper and palladium
Ivashchuk, Olga,Sorokin, Vladimir I.
scheme or table, p. 4652 - 4658 (2009/10/02)
A series of polykis(pyrazol-1-yl)benzenes, potential chelating ligands for transition metals, have been prepared by nucleophilic substitution of fluorine in 1,2-difluoro-, 1,2,3,4-tetrafluoro-, 1,2,4,5-tetrafluoro-, and hexafluorobenzenes. The observed su
