Abstract
The red compound obtained by coupling diazotised 2-nitro-4-toluidine and acetoacetanilide at higher temperatures has been shown by the X-ray crystal-structure analysis of its dibromo-derivative to be α-(4-methyl-2-nitrophenylazo)acetanilide. A three-dimensional analysis using 1061 structure amplitudes was refined to R= 9·9%. The molecule is planar and the configuration of the carbon atom to which coupling occurs is trigonal. There is the unconfirmed possibility of two intramolecular hydrogen bonds.Keywords
