Reaction between Dithiirane 1-Oxides and a Platinum(0) Complex

Abstract

Treatment of dithiirane 1-oxides 9 with (Ph3P)2Pt(η2-CH2=CH2) (3) yielded the corresponding four-membered (sulfenato−thiolato)PtII complexes 7 in high yields. The structures of 7 were determined by 31P NMR spectroscopy and, for 7e, X-ray crystallography. Treatment of dithiirane 8 with 3, on the other hand, gave the (η2-thiocarbonyl)platinum complex 10 and not the dithiolato PtII complex 4. (© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
