In a search for routes to alkynylplatinum(IV) species, we have explored the reaction of hypervalent iodonium reagents with diorganoplatinum(II) complexes, resulting in a general synthetic method for the synthesis of complexes containing one alkynylplatinum moiety, and we have extended this approach to form the first simple triarylplatinum(IV) complex. 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 PtR2(CCR) groups, e.g., the 4,4'-bis(tert-butyl)-2,2'-bipyridine complexes PtIR2(CCSiMe3)(But2bpy) (R = Me, Ph); IPh2(OTf) reacts with PtPh2(But2bpy) to form the archetypal triarylplatinum(IV) complex PtIPh3(But2bpy).
