Abstract

The synthesis of the stereoisomeric 1,2-bis(3-hydroxyphenyl)ethylenediamines (1-4) from meso-1,2-bis(2-hydroxyphenyl)ethylenediamine and 3-methoxybenzaldehyde by a diaza-Cope-rearrangement and subsequent ether cleavage with BBr3 and their conversion into the [1,2-bis(3-hydroxyphenyl)ethylenediamine]dichloroplatinum(II)-complexes with K2PtCl4 (1-PtCl2 - 4-PtCl2) is described.
