    Decacarbonyldimanganese(0) complex, Mn2(CO)10, has been evaluated

    as a catalyst for hydrosilylation reactions of 1-hexene with tertiary silanes,

    Et$iH and (EtO)3SiH. The reaction of Et3SiH appears to be first order with

    respect to the catalyst, to the hexene and to the silane, although catalyst

    deactivation occurs when relatively high silane concentrations are used. The

    reaction rate is slightly affected by varying the type of the silane used. The

    rate of disappearance of the tertiary silane is consistent with that of the

    l-hexene, which means that the catalyst is selective to hydrosilylation

    reactions. This was confirmed by following the rates of disappearance of

    Si-H and C=C IR bands at 2210, 2100 and 1650 cm-’ for (EtO)sSiH,

    Et&H and l-hexene respectively. A comprison of the behaviour of

    Mn2(CO)10 with that of Co2(CO)8 is reported here, together with a suggested

    mechanism for the manganese catalyst.
