Addition of [I(py)2]BF4 to Ru(CCH)(dppe)Cp∗ gave the iodovinylidene [Ru(CCHI)(dppe)Cp∗]BF41, which could be deprotonated to Ru(CCI)(dppe)Cp∗ 2. The attempted preparation of Ru(CCCCI)(dppe)Cp∗, followed by derivatisation with tcne, gave the dienynyl Ru{CCC[C(CN)2]CIC(CN)2}(dppe)Cp∗ 3. The Pd(0)/Cu(I)-catalysed reaction of 3 with Ru{CCCCAu(PPh3)}(dppe)Cp∗ afforded Ru{CCCC(CN)2CC(CN)2Au(PPh3)}(dppe)Cp∗ 4 by formal replacement of I+ by [Au(PPh3)]+. XRD structures of 1–4 are reported.
