Abstract
In the search for more environmental friendly dyes, the synthesis of new 1: 2 iron complexes of 1,5-diaryl-3-cyanoformazanes was carried out. The struc ture and colouristic properties of 16 new dyes and their intermediates was characterised by H-1 NMR, FAB and UV-VIS spectroscopy. The products were us ed as acid dyes in the coloration of wool and polyamide fibres. Application , colouristic and fastness properties of the dyes were determined and discu ssed.
