Ruthenium-Catalyzed Transformation of Aryl and Alkenyl Triflates to Halides
Aryl triflates were transformed to aryl bromides/iodides
simply
by treating them with LiBr/NaI and [Cp*RuÂ(MeCN)<sub>3</sub>]ÂOTf. The
ruthenium complex also catalyzed the transformation of alkenyl sulfonates
and phosphates to alkenyl halides under mild conditions. Aryl and
alkenyl triflates undergo oxidative addition to a rutheniumÂ(II) complex
to form η<sup>1</sup>-arylruthenium and 1-ruthenacyclopropene
intermediates, respectively, which are transformed to the corresponding
halides
