Resumo

Condensation of carotinoid polyene dialdehydes, 1,1′-ferrocene dialdehydes and of 9-ferrocenyl-2,7-dimethylnonatetraenal with the Fischer carbene complexes (OC)5WC(NMe2)CH2SiMe3 or (OC)5MC(Me)(OMe) (MCr, W) in the presence of n-BuLi or SiMe3Cl/NEt3 yields the bis(carbene) complexes 1–4 and the donor acceptor substituted complexes 5, 6. The star-shaped trinuclear molecules 7 and 8 were obtained under Wittig conditions from 1,3,5-tris[(triphenylphosphonio)methyl]benzene tribromide and ferrocene aldehyde or 9-ferrocenyl-2,7-dimethyl-nonatetraenal.
