On the Synthesis and Characterization of 3-Arylamino-7-nitro-2H-1,4-benzoxazines

Horst Hartmann; Roxana Barbieru; Walter Grahn; Dominic Pratt; Peter G. Jones

By the reaction of 7-nitro-2H-1,4-benzoxazin-3(4H)-one with POX 3 (X = Cl, Br) and subsequent addition of arylamines, a series of coloured 3-arylamino-7-nitro-2H-1,4-benzoxazines have been synthesized and spectroscopically characterized in order to investigate their availability as hair colorants.
