Problems solved by technology

In short, despite the extensive literature on macrocycles and transition metal complexes, crosslinking bridged tetraaza- and pentaazamacrocycles appear to be relatively unreported and not explicitly derived from the extensive chemical literature. Identify these substances, either alone or in their transition metal complexes, used in bleaching detergents

Embodiment 1

[0345] Example 1 - [Mn(Bcyclam)Cl 2 ]Synthesis

[0346]

[0347] (a) Method 1

[0348] "Bcyclam" (5,12-dimethyl-1,5,8,12-tetraazabicyclo[6.6.2]hexadecane) was developed by G.R.Weisman et al., in Journal of the American Chemical Society (J. Amer. Chem. Soc.), (1990), 112 , Prepared by the synthetic method described in 8604. Dissolve Bcyclam (1.00 g, 3.93 mmol) in anhydrous CH 3 CN (35ml, from CaH 2 distilled). The solution was then evacuated at 15 mm pressure until CH 3 CN started to boil. The flask was then connected to atmospheric pressure Ar. This degassing step was repeated 4 times. Under Ar atmosphere, adding according to H.T.Witteveen et al. Journal of Inorganic Nuclear Chemistry (J. Inorg. Nucl. Chem.) (1974), 36 , Mn(pyridine) synthesized by the method in 1535 2 Cl 2 (1.12 g, 3.93 mmol). The cloudy reaction solution slowly started to turn black. After stirring overnight at room temperature, the reaction solution turned dark brown with su...

[0356] Will press H.Yamamoto and K.Maruoka's Journal of the American Chemical Society (J. Amer. Chem. Soc.), (1981), 103 , Tetracycloadduct I (3.00 g, 13.5 mmol) prepared by the method described in 4194 was dissolved in anhydrous CH 3 CN (50ml, from CaH 2 distilled). Under Ar atmosphere, 1-iodobutane (24.84 g, 135 mmol) was added to the stirred solution. The solution was stirred at room temperature for 5 days. 1-Iodobutane (12.42 g, 67.5 mmol) was added and the solution was stirred at room temperature for an additional 5 days. Under these conditions, by 13 C-NMR shows, I Completely 1-iodobutane-alkylated. Methyl iodide (26.5 g, 187 mmol) was added and the solution was stirred at room temperature for an additional 5 days. The reaction was filtered u...

Abstract

Laundry or cleaning composition comprising: (a) an effective amount, preferably from about 0.0001 % to about 99.9 %, more typically from about 0.1 % to about 25 %, of a bleach activator and / or organic percarboxylic acid; (b) a catalytically effective amount, preferably from about 1 ppb to about 99.9 %, of a transition-metal bleach catalyst which is a complex of a transition-metal and a cross-bridged macropolycyclic ligand; and (c) at least about 0.1 % of one or more laundry or cleaning adjunct materials, preferably comprising an oxygen bleaching agent. Preferred compositions are laundry compositions and automatic dishwashing detergents which provide enhanced cleaning / bleaching benefits through the use of such catalysts in combination with bleach activators and / or organic percarboxylic acids.

Description

field of invention [0001] The present invention relates to detergent and detergent additive compositions and methods of their use. The composition comprises selected transition metals such as Mn, Fe or Cr with selected large polycyclic rigid ligands, preferably cross-linked large polycyclic ligands with bleach activators and / or organic percarboxylic acids, Combinations of hydrophobic and / or hydrophilic bleach activators are preferred. More particularly, the present invention relates to the catalytic oxidation of soils and stains and the inhibition of dye transfer during laundering of fabrics, said soils and stains using cleaning compositions comprising bleach activators and / or organic percarboxylic acids and said metal catalysts. For example on surfaces such as fabrics, dishware, counter tops, dentures, etc. The composition comprises a bleach activator and / or an organic percarboxylic acid, a detergent adjunct component and a catalyst, wherein the catalyst comprises a combina...
