合成一种有特殊稳定性的新的铑配合物 ,通过对其结构及表征数据的研究 ,发现含未配位原子是其高稳定性的主要原因所在。因为中心原子铑和它附近的未配位原子能发生分子内取代反应从而避免了铑由于失去羰基造成的分解损失。为了证实 ,同时用一种和它结构相似但没有未配位原子的铑配合物进行了对比。结果证实 ,未配位原子的存在增加了催化甲醇羰基化的配合物的稳定性。
Synthesis of a new rhodium complex with special stability, through the study of its structure and characterization data found that the uncoordinated atom is the main reason for its high stability. Because rhodium center atoms and its adjacent uncoordinated atoms can occur intramolecular substitution reaction so as to avoid rhodium loss due to the loss of carbonyl decomposition. In order to confirm, at the same time with a structure similar to it but no uncoordinated rhodium complexes were compared. The results demonstrate that the presence of uncoordinated atoms increases the stability of the complex catalyzing methanol carbonylation.
