1) Heating Cl₅W-(C(Me)₂)-CH₃ 
2) C₅H₁₁Br + Mg
3) Fe(C₅H₁₀)₂ + I₂

what if anything would be produced by these reactions please.
I thought maybe Br₂ gas on number 2.

I think for number 2, it will result in Grignard reagents which is C₅H₁₁MgBr

1) I believe this would result in the oxidation of the tungsten to form a dimerized coordination complex with a W-W bond.
2) This would form the Grignard reagent C₅H₁₁MgBr, as victor has already noted.
3) Are you sure the first compound here is not Fe(C₅H₅)₂ (ferrocene)?  If it is, the reaction you are looking for might be the oxidation-reduction reaction between ferrocene (oxidized) and iodine (reduced).

Thank`s for replies.
1) anymore help on this one?
3) no, it`s the correct formula, maybe a made up one for theory purposes

Would 1) just rearrange the groups?
Like the one or more methyl`s swap with chlorine`s.
there is only one tungsten atom, so I can`t see how a W-W bond arise.

[zjm022243]

the products of reaction 2) would be Grignard reagents

[Morphic flip]

It`s 1) I still can`t fathom.

[Mitch]

One of the products from 1 being heated should most likely be Cl2.

I wondered about that , but it`s apparently just one product formed upon heating - if any.
