Abstract

The preparation and characterisation of iron(II) complexes bearing unsymmetrically 1,4-disubstituted n?³-butenynyl ligands, cis-[Fe(C(C=CR)=C(H)R')(dmpe)₂][PF₆] (e.g. R = tBu, R' = Ph 2e; R = Ph, R' = tBu 2e') are reported. The complexes were obtained as a mixture by protonation and rearrangement of the bis(acetylido)iron(II) complex trans-Fe(CCPh)(CCtBu)(dmpe)₂. The complexes 2e and 2e' were separated by crystallisation and were both characterised, crystallographically. In addition, a number of complexes with symmetrically 1,4-disubstituted butenynyl ligands cis[Fe(C(C=CR)=C(H)R)(dmpe)₂][PF₆] (R = p-C₆H₄-OMe 2a; pC₆H₄-Me 2b, C ₆H₃-3,5-(CF₃)₂ 2c; 1-adamantyl 2d) were synthesized by protonation and rearrangement of the corresponding bis(acetylido)iron(II) complexes. © 2010 Wiley-VCH Verlag GmbH & Co.
