Oxidative additions on indenyl rhodium complexes bearing the hemilabile homoallyldiphenylphosphane (HADPP) ligand

Oxidative additions of halogens and methyl iodide on complex [Rh(η5-C9H7){κ3(P,C,C′)-Ph2PCH2CH2CHCH2}] (1) have been carried out. The addition of bromine leads to the complexes [Rh(η5-C9H7)Br2{κ1(P)-Ph2PCH2CH2CHCH2}] (4) or [Rh(η5-C9H7)Br2{κ1(P)-Ph2PCH2CH2CHBrCH2Br}] (5) depending on the reaction conditions. s on the oxidative addition of methyl iodide show up the influence of the ring slippage of the five member ring of the indenyl ligand in these reactions.
