Nucleophilic attack by O or N upon reaction of chloromethylplatinum(II) phosphine complexes with MeOH–Me2NCH(OMe)2; X-ray structure of [(Ph2PCH2CH2PPh2)Pt(CH2)2NMe2]+PF6–

Abstract

MeOH–Me₂NCH(OMe)₂ reacts with trans-(R₃P)₂Pt(CH₂Cl)Cl (R = c-C₆H₁₁ or Et) to give the methoxymethyl complexes trans-(R₃P)₂Pt(CH₂OMe)Cl, and with Ph₂P(CH₂)_nPPh₂Pt(CH₂Cl)₂(n= 2, 3 or 4) to give the 3-platina-azetidinium salts [Ph₂P(CH₂)_nPPh₂Pt(CH₂)₂NMe₂]⁺Cl^–(n= 2, 3 or 4); reaction of Ph₂P(CH₂)₂PPh₂Pt(CH₂Cl)₂ with isopropylamine gives the 3-platina-azetidine.
