Abstract
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).File in questo prodotto:
