dc.description.abstractThe (dpms)PtII complexes (dpms = di(2-pyridinyl)methanesulfonate)derived from some cyclic olefins can be readily oxidized to PtIV oxetanes, followed by reductive elimination to produce corresponding epoxides. A catalytic version of this reaction can potentially be achieved if decomposition of active species responsible for olefin substitution is avoided. Several attempts were made to solve this problem, and a more hydrophilic analog of the dipyridinemethanesulfonate ligand was obtained. Furthermore, the reductive elimination step of PtIV oxetanes was studied by using diastereomeric cis- and trans-2-butene derivatives. We believe that two mechanisms of C O reductive elimination may be involved in these reactions and that steric repulsion between substituents at the oxetane carbon atoms may play a major role in determining the predominant of the two competing mechanisms. Platinum(IV) η1-butanone complex was synthesized and characterized, which was found to undergo different types of elimination reaction to give a series of butane derivatives as products.en_US
