Abstract

The lithium salt (L)Li(THF) (L^- = bis(3,5-di-tertbutylpyrazol-1- yl)-1-CH₂NAr1 Ar = 2,6-ⁱPr₂C₆H ₃) can be readily prepared from lithium bis(3,5-di-tertbutylpyrazol- 1-yl)methide and the N-methyleneaniline H₂C=NAr. This N,N,N′-heteroscorpionate lithium reagent can be transmetalated with Tl(OTf), FeCl₂(THF)_1.5, and CoCl₂ to yield the (L)Tl, (L)FeCl, and (L)CoCl complexes, respectively. Single crystal structural data for compounds (L)Li(THF), (L)Tl, (L)FeCl, and (L)CoCl reveal in each case the hapticity of the sterically demanding, monoanionic L^- ligand to be κ³-N₃.
