摘要:
The reaction between PtCl2(PhCN)2 and N,N-dimethyl phenyl propargyl amine (1) affords trans-[Pt(N(Me2)CH2C=CPh)(NCPh)Cl2] (3) which formally undergoes trans-Cl- addition onto its C=C bond to give [Pt(C(Ph) = C(Cl)CH2NMe2)(NCPh)Cl] (4). On the other hand, the cis-nucleophilic addition product trans-{Pt[cis-(o-NC5H4) CH=C(Ph)(NEt2)]Cl2(HNEt2)} (6) was obtained quantitatively from the reaction of a large excess of diethylamine with trans-[Pt(o-NC5H4)CH=C(Ph)(SEt2)Cl2] (5).
