摘要: The reaction of Pt(IV) organometallic cyclometalated complexes type [PtXAr2(Ar′CHNCH2CH2NMe2)] to produce 5- and 7-membered Pt(II) metalacycles by a formal C–C reductive elimination/C–H oxidative addition/Ar–H elimination sequence has been studied from preparative kinetico-mechanistic perspective. detection characterization key intermediates also achieved via the careful selection conditions, including time, extracted kinetic studies. From data collected, it is clear that fine-tuning reactivity possible with respect formation alternative (i.e., [PtX(Ar-Ar′CH═NCH2CH2NMe2)] [PtX(Ar-Ar′CH═NCH2CH2NMe2)]). In all cases common occurs form non intermediate compound [PtX(Ar)(Ar–Ar′CH═NCH2CH2NMe2)], which leads selective above-mentioned actuation an unexpected equilibrium betw...
