REACTIONS AND PROPERTIES OF SOME TRIMETHYLENEPLATINUM(IV) COMPLEXES .7. KINETICS AND MECHANISM OF DISPLACEMENT OF CYCLOPROPANE BY ALKENES

The kinetics of the reaction of alkenes (e.g. cis-pent-2-ene, hex-1-ene, cyclopentene) with [PtX2(CH2CH2CH2)(THF)2] (X = Cl or Br, THF = tetrahydrofuran) or with [PtCl2(CHPhCH2CH2)(THF)2] in THF solution have been studied. The reactions occur with displacement of cyclopropane or phenylcyclopropane to give [PtCl2(olefin)(THF)], and follow essentially second order kinetics, first order in both platinum complex and olefin. The mechanism of reaction is discussed. © 1979.
