Resum
The addition of phosphine derivatives and SnX2 (X = Cl or Br) to solutions of [IrCl(COD)]2 (COD) = 1,5-cyclooctadiene) leads to the preparation of the pentacoordinated complexes [Ir(SnX3)(COD)L2], which carbonylated or hydrogenated at ordinary pressure and at room temperature yield [Ir(SnCl3(CO)2L2] or, respectively, [Ir(SnCl3)H2L2]. The latter catalyze both the hydrogenation and the isomerization of n-heptene; the rates of these reactions decrease with decreasing basicity of the phosphine. © 1980.
