Some alkynyl-ruthenium complexes containing di-imine and tertiary phosphine ligands

Abstract

Article first published online: 5 MAY 2008Reactions between [RuCl2(PPh3)2(Bu 2tbpy)], (1), and terminal alkynes in the presence of Tl[PF6], followed by chromatography on alumina, have given the mono-alkynyl complexes [RuCl(C≡CR)(PPh3)2(Bu 2tbpy)] (R = Ph 2, C6H4NO 2-4 3, CO2Me 4, Fc 5, CPh2(OH) 6), of which the single-crystal XRD molecular structures of 3, 4 and 5 are reported. © 2008 Wiley-VCH Verlag GmbH & Co.
