Abstract:	The interaction of azobenzene and MnR(CO)₅ (R  Me, Et, CH₂Ph, CH₂-C₆Me₅, COCF₃, COCH₂C₆F₅, COCH₂OPh, Ph or C₆F₅) affords M $n(C_{6} H_{4} NN$ Ph)-(CO)₄, together with a binuclear complex Mn₂(CO)₆(C₁₂H₁₀N₂) in some cases. The metallation reaction is shown to proceed most readily with Mn-(CH₂Ph)(CO)₅; with this reagent, the metallated complexes M $n(C_{6} H_{4} CH_{2} P$ Me₂)-(CO)₃[PMe₂(CH₂Ph)] (two isomers) and M $n(C_{6} H_{4} CH_{2} A$ sMe₂(CO)₄ have been obtained on treatment with EMe₂(CH₂Ph) (E  P and As, respectively).
