Reactions of RuCl(PPh3)2Cp∗ with 1-alkynes in non-polar solvents afford the neutral vinylidene complexes RuCl(CCHR)(PPh3) Cp∗ [RPh (X-ray structure), Bu1, SiMe3, CO2Me]; a novel 1,3 elimination of HCl induced by NaOMe in the presence of a variety of ligands gives the chiral-at-metal complexes Ru(CCR)(L)(PPh3)Cp∗ [LCO, C2H4 (X-ray structure), PR3, P(OR)3, O2, S2, CS2 (for example)].
