Abstract

Reaction of [Fe(CO)25-C5H 5)]2 with CF3C2CF3 affords the ferracyclohexadienone [Fe2(CO){C4(CF 3)4CO}(η5C5H5) 2], whereas [Ru(CO)25C5H 5)]2 gives sequentially the trans-insertion product [Ru{C(CF3):C(CF3):C(CF3)H}(CO) 25-C5H5)] and [R[graphic omitted]C(CF3)H(CO)(ηC5H5)]; in contrast [Fe(CO)21-C5H5) (η5-C5H5)] affords [FeCO{COC 7H5(CF3)2}(η5-C 5H5)] with CF3C2CF3 and [Fe(COCF2C5H5)(η5-C 5H5)] with C2F4, the latter reaction involving cleavage of a C-C bond.
