摘要
The detailed catalytic mechanisms on transfer hydrogenation of ketones are explored by employing the representative reaction of 3-pentanone and 2-propanol catalyzed by the model complex IrH3[(Me2PC2H4)(2)NH], derived from the catalyst IrH3[((Pr2PC2H4)-Pr-i)(2)NH], with the aid of the density functional theory calculations. The geometrical transformation from an octahedron to a Y-type involved in the catalytic cycle is also elucidated in terms of molecular theory of transition metal complexes. The trend for the variation of Ir-N bond distance is also analyzed. (C) 2007 Elsevier B. V. All rights reserved.
