Reaction of NaMn(CO)5 with trans 1-bromopenta-2,4-diene in tetrahydrofuran at -78 degC gives (η1-2,4-pentadienyl)Mn(CO)5 (1) in excellent yield.Compound 1 undergoes η1 -> syn-η3 -> η5 transformation and, yields (syn-η3-2,4-pentadienyl(Mn(CO)4 (2) and (η5-pentadienyl)Mn(CO)3 (3), respectively.The reactions of (1) with the electrophiles tetracyanoethylene (TCNE) and sulfur dioxide (SO2) were investigated.Compound 1 undergoes a cycloaddition with TCNE and an insertion reaction with SO2.The products are characterized by elemental analysis and spectroscopic data.

Mn(CO)5(η1-pentadienyl) (1) and the corresponding η1-hexadien-1-yl complex (2) undergo [4 + 2] cycloaddition with tetracyanoethylene and maleic anhydride to produce the adducts (CO)5MnCH2-CHC(CN)
