Abstract

Treatment of the 2-pyridylferrocenes [CpFe(C5H3R{C5H4N})] (R=H, Me) with HAuCl4 or NaAuCl4 in aqueous acetonitrile yields the cycloaurated complexes [CpFe(C5H2R{C5H4N}AuCl2)] (R=H, 2 a; Me, 2 b). Reaction of 2 a,b with phenylacetylene in the presence of CuI and NEt3 produces the monoalkynyl complexes [CpFe(C5H2R{C5H4N}AuI{CCPh})] (R=H, 3 a; Me, 3 b), while the reaction of 2 a with NaCN/ LiCl yields.the bis-cyanide [CpFe(C5H3{C5H4N}Au{CN}2)] 4 a. The molecular structures of 2 a, 3 a, 3 b and 4 a were determined by X-ray diffraction.
