Abstract
Condensation of carotinoid polyene dialdehydes, 1,1′-ferrocene dialdehydes and of 9-ferrocenyl-2,7-dimethylnonatetraenal with the Fischer carbene complexes (OC) 5WC(NMe 2)CH 2SiMe 3 or (OC) 5MC(Me)(OMe) (MCr, W) in the presence of n-BuLi or SiMe 3Cl/NEt 3 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.
