Information  at a Glance Contents on the CD ROM
  • 1,4,7-Triazacyclononane, known as "TACN" is a cyclic organic compound with the formula C6H12(NH)3
  • The definition of TACN is TetrAmine Copper Nitrate.
  • MnTACN is a highly efficient catalytically
    active metal complex, originally developed as a biomimetic to simulate active centers of enzymes
  • MnTACN is the powerful bleach catalyst for tea stain removal
  • MnTACN is dinuclear tri- -oxo bridged manganese(IV) complex of the ligand 1,4,7-trimethyl-1,4,7-triazacyclononane
  • Manganese-1,4,7-trimethyl-1,4,7-triazacyclononane complexes catalyse the oxidation of phenolate and cinnamate anions and sulfides by hydrogen peroxide
  • 1,4,7-trimethyl-1,4,7-triazacyclononane manganese:
    Molecular Formula C9H21MnN3
  • MnTACN catalyst is one
    of the most active catalysts for hydrogen peroxide activation in
    bleaching of stains.
  • By using environmentally benign oxidant H2O2 in combination with the proven high-performing dinuclear manganese catalyst MnTACN both short-time and low-temperature bleaching process can be accomplished.
  • The oxidation of phenols, cinnamic acids and methyl aryl sulfides by hydrogen peroxide, using three catalyst systems, [L2Mn2IV(μ-O)3](PF6)2, L = 1,4,7-trimethyl-1,4,7-triazacyclononane; [LMnIV(OMe)3(PF6); and MnII/L/H2O2, have been studied. The results from a combination of spectroscopic and kinetic studies, coupled with Hammett correlations and 18O labelling experiments, suggest that with each system the active oxidant is an electrophilic, mononuclear oxo-manganese (V) species. The influence of additives that can act as co-ligands for the manganese species has been investigated, with a view to controlling the activity/selectivity of the active oxidant. The two-step, sulfide–sulfoxide–sulfone, oxidation shows an unusual switch in the philicity of the active oxidant from electrophilic in the first step to nucleophilic in the second. Mechanisms for the oxidations are proposed.
