Synthesis of a tri(organoplatinum) complex via the double directed lithiation of a mono(organoplatinum) precursor
Abstract
The new diarylplatinum complex cis-[Pt(PEt3)2{C6H3(CH2-NMe2)2-3,5}2] 1, containing four free amine coordination sites, undergoes directed lithiation with ButLi and subsequent transmetallation with [PtCl2(SEt2)2] to give a triplatinum species 3 which reductively eliminates the diplatinum complex [ClPt{2,6-(Me2NCH2)2C6H2–C6H2(CH2NMe2)2-2,6}PtCl] 4.
