Synthesis and structural characterization of bimetallic μ-malonyl complexes

Reaction of rhenaenolate [(η 5 -C 5 Me 5 )(NO)(PPh 3 )Re(COCH 2 )] - Li + generated from (η 5 -C 5 Me 5 )(NO)- (PPh 3 )Re(COCH 3 ) and n-BuLi, with (CO) 5 M(OSO 2 CF 3 ) [M=Re, Mn] leads to good yields of the μ-η 1 ,η 2 -malonyl complexes (η 5 -C 5 Me 5 )(NO)(PPh 3 )Re[μ-(COCH 2 CO)-C 1 :C 3 ,O 1 ]M(CO) 4 (M = Re, Mn)
