✦ Synopsis
Nucleophilic addition
of malonate anion to cationic l-substituted (r$-4-methoxycyclohexadienyl)Fe(C0)2PPh3 comp!exes 6e-g proceeds predominantIy at the more substituted cyclohexadienyl terminus to afford l,l-disubstituted (q 4-4-methoxy-2.4cyclohexadiene)Fe(CO)2PPh3 complexes 7e-g in good yields.

Reaction of p-anisidine 13 or p-bromo orthoanisidine 14 with the new bi-deuterated dienyl complex 12 bearing a leaving group on its side chain affords the mono-deuterated 18a, 19a and the non-deuterated lgb and 19b spiro[1,2,3,4-tetrahydroquinoline-4,1'-cyclohexane] derivatives. The formation of the
Chelated dicarbonyl 014-4-methoxycyclohcxadiene) iron complexes 6 and 15 which possess a phosphinilc and a phosphme bridge respectively form a new class of iron complexes. Their cations 5 and 16 reacled regioseleclively with nucleophiles in good yields. The observed regioselectivities are unusual fo
