A quintuply bonded dichromium complex stabilized by aminopyridinato ligands activates CO2 and SO2 by reducing the (formal) bond order of the metal-metal bonds. Oxygen abstraction is observed during CO2 activation. SO2 activation proceeds via formation of a unique dithionite complex/coordination. Furthermore, N2O activation was investigated and the formation of a tetrameric Cr-oxo complex was observed.
一种由氨基吡啶基配体稳定的五重键二铬配合物通过降低金属-金属键的(形式)键级来活化二氧化碳和二氧化硫。在二氧化碳活化过程中观察到氧的夺取。二氧化硫活化通过形成一种独特的连二亚硫酸盐配合物/配位来进行。此外,还研究了一氧化二氮的活化,并观察到一种四聚体铬氧配合物的形成。
