The paper presents a comprehensive survey on the synthetic procedures of transition metal complexes of -pyridinyl alcoholato, -bipyridinyl alcoholato, α,α'-pyridinyl dialcoholato and α,α'-bipyridinyl dialcoholato ligands and their coordination chemistry. Greater emphasis is, however, given to the catalytic activity of the complexes in homogeneous and asymmetric chemical reactions. The multidentate character of the pyridinyl alcohols and/or bipyridinyl diols is of great importance in the complexation with a large number and type of transition metals. The transition metal complexes of pyridinyl alcoholato or bipyridinyl dialcoholato ligands in most cases, and a few pyridinyl alcohols alone, were used as catalysts in homogeneous and chemical asymmetric reactions. In most of the homogeneously catalysed enantioselective chemical reactions, limited numbers and types of pyridinyl alcohols and or bipyridinyl diols were used in the preparation of chiral catalysts that led to a few investigations on the catalytic importance of the pyridinyl alcohols.
本文对 -吡啶醇盐、-联吡啶醇盐、α,α'-吡啶二醇盐和α,α'-联吡啶二醇盐配体的过渡金属配合物的合成方法及其配位化学进行了全面综述。然而，本文更侧重于研究这些配合物在均相和不对称化学反应中的催化活性。吡啶醇和/或联吡啶二醇的多齿特性对于与大量不同类型的过渡金属的配合非常重要。吡啶醇盐或联吡啶二醇盐配体的过渡金属配合物在大多数情况下，以及少数单独的吡啶醇，被用作均相和化学不对称反应中的催化剂。在大多数均相催化的对映选择性化学反应中，仅使用有限数量和类型的吡啶醇和/或联吡啶二醇来制备手性催化剂，这导致对吡啶醇的催化重要性的研究较少。
