Benzylamidine complexes of platinum(II) derived by nucleophilic addition of primary and secondary amines. X-ray crystal structure of trans-[PtCl2{Z-N(H)C(NHMe)CH2Ph}2]
摘要:
The reaction of cis- and trans-[PtCl(2)(NCCH(2)Ph)(2)] with a 5-fold excess of MeNH(2) and Me(2)NH in CH(2)Cl(2) at -10 degrees C affords in high yield the bis-amidine derivatives cis- and trans-[PtCl(2){Z-N(H)=C(NHMe)CH(2)Ph}(2)] (1a, 2a) and cis- and trans-[PtCl(2){EN(H)=C(NMe(2))CH(2)Ph}(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-[PtCl(2){Z-N(H)=C(NHMe)CH(2)Ph}(2)] (2a).Moreover, the in vitro cytotoxicity for the new derivatives was evaluated in a wide panel of human tumor cell lines.
