Reprint requests to Prof. W. Beck. E-mail: wbe@cup.uni-muenchen.de Z. Naturforsch.2009,64b,159 – 164; received November 3, 2008

Dedicated to Professor Ingo-Peter Lorenz on the occasion of his 65thbirthday

3,4-Bisarylpyrrole-2,5-dicarboxylic acids were coupled withrac-N1,N2-di-Boc-1,2,4-triaminobut- ane to give the corresponding diamides, which were deprotected and converted into the bis(cis-di- chloroplatinum) complexes by treatment with K2PtCl4.

Key words:Pyrrole-2,5-dicarboxylic Acids, 1,2,4-Triaminobutane, Bis(ethylenediamine), cis-Dichloroplatinum Complexes
