Nucleophilic addition of malonate anion to cationic 1-substituted (eta
(5)-4-methoxycyclohexadienyl)Fe(CO)(2)PPh3 complexes 6e-g proceeds pre
dominantly at the more substituted cyclohexadienyl terminus to afford
1,1-disubstituted (eta(4)-4-methoxy-2,4-cyclohexadiene)Fe(CO)(2)PPh3 c
omplexes 7e-g in good yields. (C) 1998 Elsevier Science Ltd. All right
