Bis-o-amino(thio)phenols and their preparation

Bis-aminophenols are new. Bis-aminophenols of formula (I) are new. G = oxgyen or sulfur; M = formula (II)-(IX); R1, R2 = phenyl, -(CH2)nCH3, -G-(CH2)nCH3, -C(CH3)3, -GC(CH3)3, -(CF2)nCF3, -G-(CF2)nCF3, -G-CH(CH3)2, -CH(CH3)2, -CF(CF3)2, -C(CF3)3, -N(CH3)2, -N(CF3)2, -C(R1)(R2)-, -C(O)-, -O-, -S- or -N(R1)-; n = 0-5. An Independent claim is included for a process for the preparation of bis-aminophenols (I) by reaction of a diol (II) to form a nitroso compound followed by reduction to form the bis-aminophenol (I).
