Abstract The reactions of the organometallic enolates [η 5 -C 5 H 4 C(O)CH 3 ]Fe(η 5 -C 5 H 4 C(O)CH 2 ] − and [Cp(Ph 3 P)(OC)FeC(O)CH 2 ] − with [(CO) 3 M(C 7 H 7 )] + (M = Cr, Mo) proceed with CC coupling and give the complexes (η 5 -C 5 H 4 C(O)CH 3 )Fe[η 5 -C 5 H 4 C(O)CH 2 (η 6 -C 7 H 7 )M(CO) 3 ( 1a,b ) and Cp(Ph 3 P)(OC)FeC(O)CH 2 (η 6 -C 7 H 7 )M(CO) 3 ( 2a,b ), rescpectively. CpFe[η 5 -C 5 H 4 C(O)Re(CO) 5 ] ( 3 ) is obtained from CpFe[η 5 -C 5 H 4 C(O)Cl] and Re(CO) 5 − . The structures of 1b and 3 have been determined by X-ray diffraction.
