The review presents state-of-the-art data on the influence of catalysts (mainly transition metal complexes) on the regioselectivity of a number of reactions. The most important addition reactions to unsaturated bonds are considered, in particular, hydroformylation, hydrosilylation, hydroboration and hydroxy-, alkoxy- and aminocarbonylation, which give predominantly one product. Particular attention is given to reactions with divergent regioselectivity. The reaction conditions, the structures of metal complexes and the ligands involved are indicated and, in some cases, the reaction mechanism is discussed. Examples of industrial processes using homogeneous catalysis are given.

The bibliography includes 203 references.

该综述提供了有关催化剂（主要是过渡金属配合物）对许多反应的区域选择性影响的最新数据。考虑对不饱和键的最重要的加成反应，特别是加氢甲酰化、氢化硅烷化、硼氢化和羟基-、烷氧基-和氨基羰基化，它们主要产生一种产物。特别注意具有不同区域选择性的反应。指出了反应条件、金属配合物的结构和涉及的配体，在某些情况下，还讨论了反应机理。给出了使用均相催化的工业过程的例子。
