Abstract

FIELD: organic chemistry, bleaching agents. ^ SUBSTANCE: invention relates to catalytic bleaching substrates, for example, fabrics in laundering with atmospheric oxygen or air. Invention describes a bleaching composition containing substance of the formula L in an aqueous medium that forms complex with transient metal being this complex catalyzes bleaching substrate with atmospheric oxygen and an aqueous medium doesn't comprise essentially a peroxygenic bleaching agent, or based on peroxide, or a bleaching system based on thereof wherein L represents ligand forming complex of the general formula: [MaLkXn]Ym wherein M means metal taken among Mn, Fe, Co, Ni and Ru; X means a coordinating product taken among any mono-, bi- or tri-charged anions and any neutral molecules that are able to coordinate a metal by mono-, bi- or tridentate method; Y means any non-coordinated counterion; a = 1-10; k = 1-10; n = 0 or 1-10; m = 0 or 1-20; L represents ligand of the general formula (BI) or its analogue with joined or removed proton: ^ ^ wherein g = 0 or 1-6; r = 1-6; s = 0 or 1-6; Z1 and Z2 represent independently of one another heteroatom or heterocyclic or heteroaromatic ring wherein Z1 and/or Z2 are substituted optionally with one or some functional groups E comprising values indicated below; Q1 and Q2 represent independently of one another group of the formula : ^ ^ wherein d = 0-9; e = 0-9; f = 0-9; each among Y1 is taken among -(G1)N-, -(G1)(G2)N- (wherein G1 and G2 have values indicated below), -C(O)-, arylene, alkylene; R1, R2, R6, R7, R8 and R9 represent independently of one another group taken among hydrogen atom, hydroxyl, -OR (wherein R means alkyl, alkenyl, cycloalkyl, heterocycloalkyl, heteroaryl or carbonyl-derivative group), -OAr, alkyl, alkenyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl and carbonyl-derivative groups. Each among R, Ar, alkyl, alkenyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl and carbonyl-derivatives groups is substituted optionally with one or some functional groups E; E is taken among functional groups comprising nitrogen atom and any electron-donor and/or acceptor groups; T1 and T2 represent independently of one another groups R4 and R5 wherein R4 and R5 have values indicated for R1-R9. Invention describes a method for bleaching substrate involving application of a bleaching composition in an aqueous medium on its. Invention provides the possibility for using atmospheric oxygen (air) as a source for bleaching that provides the economy benefit and safety for the environment. ^ EFFECT: improved bleaching method, valuable properties of composition. ^ 2 tbl, 8 ex
