The purpose - search of original methods of synthesis 3,3 ', 4,4 '- tetraaminodiphenyle. These methods will allow to avoid obtaine or use high cancerogenic benzidine and other toxic compounds, and be able consist a minimum number of steps and will provide high yield of a main product. The analysis of the literatury data has allowed to bleed over ten possible schemes of synthesis 3,3 ', 4,4 '- tetraaminodiphenyle. The carried out research has shown, that only two are perspective as allow to avoid use of cancerogenic substances and provide enough high yield of a main product. 4-Chloro-1,2-phenylendiamine is the starting compound, which in three steps: protection of amino groups, doubling and reduction - yields target connection in first method. In the second - the role of starting plays 4-chlore-2-nitroaniline which as a result of similar three steps synthese yields target product with high yield too.
