Levinson, F. S. published the artcileEvaluation of the Effect of the Furazane Fragment on the NH Acidity of 4- and 5-Picrylaminobenzofurazanes in DMF and DMSO, Product Details of C6H5N3O, the publication is Russian Journal of General Chemistry (2005), 75(6), 933-935, database is CAplus.
The products of the reactions of picryl chloride with isomeric aminobenzofurazans in DMF and DMSO were studied by nonaqueous potentiometric titration The effect of the position of the furazan fragment in 4- and 5-picrylaminobenzofurazans on the NH acidity is considered. The electron-acceptor properties of the furazan fragment were evaluated via inclusion of the resulting data into the pK a-σ correlation for 2,4,6-trinitrodiphenylamines. On this basis, conventional Hammett σ constants were calculated for the furazan fragment located in the immediate vicinity of the N-H center and one position distant from it.
