SUMMARY:Organometallic Reaction Chemistry and Catalysis in the Solid-State

DESCRIPTION:Organometallic Chemistry is dominated by structures\, transfor
 mations and catalysis that occur in the solution phase.  However\, this is
  not always the most desirable phase to operate in.  For example: when cat
 alysis requires separation of catalyst and substrates/products\, selectivi
 ty in transformations that is promoted by solid-state effects is required\
 , when solvent reacts unfavourably with the metal complex or when the host
 -guest properties of crystalline lattices encourage the formation of compl
 exes that are difficult to prepare in solution phase.\n\nThis talk will ou
 tline our recent investigations that explore whether similar organometalli
 c structures\, transformations and catalysis can occur in the solid-state\
 , when compared to the analogous solution-phase chemistry\, using group 9 
 (Rh and Ir) phosphine complexes.  It will demonstrate\, by comparison with
  solution-phase chemistry\, that C-H\, C-Cl activation\, C-C bond formatio
 n and activation can all occur in the solid-state.  Furthermore we discuss
  the characterisation of interesting intermediates in these transformation
 s that invoke sigma interactions between the organic fragment and the meta
 l centre: C-H alkane complexes and C-C sigma complexes.
