Abstract

The prepn. of stereoisomeric 1,2-bis(3-hydroxyphenyl)ethylenediamines (L) 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 to PtLCl2 with K2PtCl4 are described. PtLCl2 were characterized by CD, IR and NMR spectra.
