Intramolecular cyclization of (eta(4)-diene)Fe(CO)(3) complexes bearing a c
arboxylic acid chloride functionality at the terminal side chain of the die
ne ligand produces (sigma, eta(3)-allyl)Fe(CO)(3) complexes, whereas treatm
ent of the acid chloride complexes with Et3N and AlCl3 provides (eta(4)-die
ne)Fe(CO)(3) complexes containing a cyclopentanone moiety. (C) 2000 Elsevie
