Abstract

The reaction of phenyl(alkynyl)iodine(III) triflates with diorganoplatinum(II) complexes provides a general route for the synthesis of a new class of alkynylplatinum(IV) complexes containing ptIVR 2(C≡CR2) groups, e.g., the 4,4′ -bis(tert-butyl)-2,2′bipyridine complexes PtIR2(C≡ CSiMe3)(Bu2′-bpy) (R = Me, Ph); IPh2(OTf) reacts with PtPh2(Bu2′bpy) to form the first archetypal triarylplatinum(IV) complex PtIPh3(Bu2′ bpy). © 2003 Elsevier B.V.
