Reaction sequences involving trans-(p-tol)-(Ar3P)2PtCl (Ar = Ph, p-tol), HC≡CC≡CH, HC≡CSiEt3, and oxidative ≡CH/HC≡ cross- or homocoupling (O2, cat. CuCl/TMEDA) give the Cx complexes trans,trans-(p-tol)(Ar3P)2Pt(C≡C) nPt(PAr3)2(p-tol) (n = 4, 6), which have been characterized by crystallography and by IR, NMR, and UV-visible spectroscopy.
