A new class of ligands derived from benzo[h]quinoline are described and these ligands are used to prepare several novel transition metal complexes. The complexes are preferably of the group VIII transition metals iron, ruthenium or osmium, with the benzo[h]quinolone ligands acting as tridentate ligands. The complexes described are proved to be very active catalysts for the reduction of ketones and aldehydes to alcohols, via hydrogen transfer and hydrogenation reactions. These compounds hence can be usefully employed as catalysts in said reduction reactions.
本文描述了一类由苯并[h]喹啉衍生的新配体,并利用这些配体制备了几种新型过渡金属配合物。这些配合物最好是第八族过渡金属铁、钌或锇的配合物,苯并[h]喹啉配体作为三叉配体。事实证明,所述配合物是非常活跃的催化剂,可通过氢转移和氢化反应将酮和醛还原成醇。因此,这些化合物可在上述还原反应中用作催化剂。
