Abstract
Oxidation of monocyclometalated platinum(II) complexes results in octahedral platinum(IV) complexes. Depending on the substitution, two different reactions occur: either a simple isomerization, resulting in the exchange of ligand positions, or a reductive coupling of aryl chloride. With a doubly cyclometalated complex, stability of the oxidized form is dependent on isomeric form: whereas the trans isomer is robust, being manipulable in air at room temperature, the cis isomer decomposes at -20 °C and above. Reductive coupling at this cis isomer is 100% selective for alkyl chloride over aryl chloride and is suggested to be a concerted process. © 2012 American Chemical Society.
