Ruthenocenylacetylene reacted with trans-PtI(C6H4X-p)(PPh3)2 (X = H, Me, OMe, Cl or CO2Me) in the presence of CuI in diethylamine-CH2Cl2 to give the Pt(II) ruthenocenylacetylide complexes, trans-Pt(C=CRc) (C6H4X-p)(PPh3)2 with a good yield. Similarly, cis-Pt(C=CRc)(C6H4OMe-p)(dppe) was prepared. The structure of trans-Pt(C=CRc)(C6H4CO2Et-p)(PPh3)2 was determined by single-crystal X-ray diffraction. No reaction of the trans isomers with DDQ or AgBF4 took place, while the cis isomer was oxidized with AgBF4 to give the coupling products RcC=CC6H5OMe-p with a low yield. The oxidation of the cis isomer with iodine occurred on the Pt atom to afford p-MeOC6H4I and PtI2(dppe) as the main products.
