在饱和的碳原子和过渡金属原子之间有单键的化合物是非常重要的。姑且不说在天然的维生素B_(12)体系内钴-碳键的意义和作用,以及在其它生物体系内可能存在金属-碳键,我们只需考虑到:就在我现在发表演讲的同时,即使没有几万吨至少也有几千吨的化合物在工业上正进行着反应和合成出来,在这些流程中的某些阶段也包括着过渡金属-碳键。一般人大概都熟悉:用聚乙烯和聚丙烯可以做成家庭用具、包装材料及孩子们的玩具等等。这些材料是由Ziegler-Natta或Philipps分别用钛和铬催化制成的。而且在其它聚合物、合成橡胶以及用作为工业溶剂或中间体的各种简单化合物的合成中,过渡金属化合物都可用作催
It is important that compounds have a single bond between a saturated carbon atom and a transition metal atom. Not to mention the significance and role of the cobalt-carbon bond in the natural vitamin B_ (12) system and the possible presence of metal-carbon bonds in other biological systems, we only need to consider that while I was giving my speech now, Even thousands of tons of at least thousands of tons of compounds are being reacted and synthesized in the industry, including transition metal-carbon bonds at some stages in these processes. Most people are probably familiar with: polyethylene and polypropylene can be made into household appliances, packaging materials and children’s toys and so on. These materials are catalyzed by Ziegler-Natta or Philipps with titanium and chromium, respectively. Also in the synthesis of other polymers, synthetic rubbers, and various simple compounds for use as industrial solvents or intermediates, transition metal compounds are useful as catalysts
