Abstract :
The reaction of cis- and trans-[PtCl2(NCCH2Ph)2] with a 5-fold excess of MeNH2 and Me2NH in CH2Cl2 at −10 °C affords in high yield the bis-amidine derivatives cis- and trans-[PtCl2{Z-N(H)C(NHMe)CH2Ph}2] (1a, 2a) and cis- and trans-[PtCl2{E-N(H)C(NMe2)CH2Ph}2] (3a, 4a), respectively. The complexes were characterized by means of elemental analysis, multinuclear NMR and FT-IR techniques. The X-ray diffraction analysis was carried out for trans-[PtCl2{Z-N(H)C(NHMe)CH2Ph}2] (2a).
er, the in vitro cytotoxicity for the new derivatives was evaluated in a wide panel of human tumor cell lines.
