Cultural advice

The Australian National University acknowledges, celebrates and pays our respects to the Ngunnawal and Ngambri people of the Canberra region and to all First Nations Australians on whose traditional lands we meet and work, and whose cultures are among the oldest continuing cultures in human history.

Aboriginal and Torres Strait Islander peoples are advised that ANU Library collections may include images, names, voices, and other representations of deceased persons.

dc.description.abstractReaction of RuHCl(CO)(PPh3)3 with aryl alkynes HCCC6H4R-4 [1: R = N(C6H4Me-4) 2 (a), OMe (b), Me (c), CO2Me (d), NO2 (e)] gives the five-coordinate vinyl complexes Ru(CHCHC6H 4R-4)Cl(CO)(PPh3)2 (2a-e). Reaction of 2a with excess PMe3 gives crystallographically characterised Ru{CHCHC 6H4N(C6H4Me-4)2-4}Cl(CO) (PMe3)3 (3a), whilst reaction of 2a-e with KTp affords Ru(CHCHC6H4R-4)(CO)(PPh3)Tp (4a-e) bearing the facially capping Tp- ligand. Electrochemical and spectroelectochemical properties of 4a-e are consistent with substantial redox activity associated with the vinyl ligand, and these properties have been satisfactorily modelled by DFT based calculations of electronic structure.
