Synthesis and properties of hydrophobic [MnIV2(μ-O)3(L)2]2+ complexes, derived from alkyl substituted 1,4,7-triazacyclononane ligands
摘要:
A series of manganese complexes of 1,4,7,-trimethyl-1,4,7-triazacyclononane homologues has been prepared. The ligand bears on position 1 or 2, alkyl and/or benzyl substituents resulting in an increase of lipophilicity of the coordination complex measured by the log P values. The lipophilic complexes dissolve well in organic solvents like dichloromethane. This permits them to be used as homogenous catalysts in two phase epoxidation of lipophilic substrate like styrene and dodecene using hydrogen peroxide as oxidant. Also the most lipophilic complexes activate hydrogen peroxide for bactericidal activity. (C) 1999 Elsevier Science S.A. All rights reserved.
