讨论了有机合成中 C-C 和 C-杂原子键形成的现有技术以及均相和多相催化的前景。对于溶液中发生的反应，考虑由单个金属原子和多个金属原子表示的催化剂中心之间的关系。从机理的角度强调了液相浸出和催化剂演化对催化剂活性、选择性和稳定性的影响。比较了金属纳米粒子和“纳米盐”类型的催化剂构建新的 C-C 和 C-杂原子键。
The current state of the art and perspectives of homogeneous and heterogeneous catalysis are discussed for C-C and C-heteroatom bond formation in organic synthesis. The relationship between catalyst centers represented by a single metal atom and by multiple metal atoms is considered for reactions taking place in solution. The influence of leaching and catalyst evolution in the liquid phase on the activity, selectivity, and stability of the catalyst is highlighted from a mechanistic point of view. Metal nanoparticle and "nanosalt" types of catalysts are compared for constructing new C-C and C-heteroatom bonds.
