Abstract
Dinitrogen complexes of the type Tp(R,R)Cr-N2-CrTp(R,R) are not the most labile precursors for Cr(i) chemistry, as they are sterically protected from obligatory associative ligand substitution. A mononuclear alkyne complex - Tp(tBu,Me)Cr(η(2)-C2(SiMe3)2) - proved to be much more reactive.
摘要
Tp(R,R)Cr-N₂-CrTp(R,R) 类型的二氮配合物并非Cr(i)化学中最不稳定的前体，因为它们在空间上受到保护，不会发生必然的缔合配体取代反应。一种单核炔烃配合物——Tp(tBu,Me)Cr(η(2)-C₂(SiMe₃)₂)——被证明反应活性要高得多。
