羰基钴簇合物Co_2(CO)_8可用于有机合成的催化剂。但Co_2(CO)_8本身不稳定,易被氧化。因此,研究不向CO_2簇合物的稳定性及其催化性能具有一定的意义。实验表明,用快烃RC_2R′(R=R′或R(?)R′)取代Co_2(CO)_8中的2个Co所生成的新型簇合物(RC_2R′)Co_2(CO)_6就比Co_2(CO)_8稳定得多。
Co2 (CO) _8 can be used as a catalyst for organic synthesis. However, Co_2 (CO) _8 itself is unstable and easily oxidized. Therefore, the research does not have a certain significance to the stability of the CO 2 cluster and its catalytic performance. The experimental results show that the new cluster (RC_2R ’) Co_2 (CO) _6 produced by replacing two Co in Co_2 (CO) _8 with fast RC_2R’ (R = R ’ Co_2 (CO) _8 is much more stable.
