PLATINUM(IV) COMPLEXES OF VICINAL-1,2-DIAMINES AND BIS(VICINAL-1,2-DIAMINES) WITH AN ACYLAMINO FUNCTION - EVIDENCE FOR A PLATINUM HYDROPEROXIDE INTERMEDIATE UPON OXIDATION

摘要

By oxidation of mononuclear and dinuclear platinum(II) complexes having as ligands N4-acylated 1,2,4-triaminobutane units with H2O2 an intermediate was observed, probably a platinum bound hydroperoxide which is stabilized by hydrogen bonding to the acyl function in the side chain. Such an intermediate could not be isolated in the oxidation of [Cl2PtLLPtCl2] to the platinum(IV) complexes [(Ho)(2)Cl2PtLLPtCl2(OH)(2)] (LL = 1,2,9,10-tetraaminodecane or 1,2,11,12-tetraaminododecane). The synthesis of several mononuclear and dinuclear diamine tetrachloro platinum(IV) complexes is reported. (C) 1997 Elsevier Science S.A. [References: 35]
