Metalation of Aryl‐bis(3‐alkyl‐5‐methylpyrazol‐1‐yl)methane (Alkyl = Me, Ad; Aryl = Ph, C6H4‐2‐OH) with NaN(SiMe3)2, KN(SiMe3)2, and Ca{N(SiMe3)2}2

Research ArticleDeprotonated aryl-bis(pyrazolyl)methanes (C-heteroscorpionates) are valuable oligodentate ligands in coordination chemistry. Commonly, they are regarded as stable and inert ligand systems. Here, we demonstrate that these C-heteroscorpionate ligands easily degrade in the vicinity of divalent cations and show stabilization strategies.
