Oxidative addition reaction of perfluoro-n-butyl iodide to (COD)PtMe2 to give (COD)PtMe(nC4F9).: The molecular structure of (COD)PtMe2

Reaction of (COD)PtMe2 (COD = 1,5-cyclooctadiene) with one molar equivalent of C4F9I in hexanes produces the perfluoroalkylplatinum product (COD)PtMe(C4F9) (1) along with the known Pt(IV) complex [PtMe3I](4). This result stands in contrast to previous reports that attempts to synthesize platinum complexes with fluoroalkyls larger than CF3 gave only inseparable mixtures. An essential condition to the controlled synthesis of 1 is the use of only one equivalent of perfluoroalkyl iodide. Similar reactions reported previously employed an excess of iodoperfluorocarbon, which gave rise to mixtures of products due to successive oxidative addition and reductive elimination reactions. The X-ray crystal structure (COD)PtMe2 was determined. (C) 2002 Elsevier Science Ltd. All rights reserved.
