摘要
The lithium salt (L)Li(THF) (L- = bis(3,5-di-tertbutylpyrazol-1-yl)-1-CH2NAr, Ar = 2,6-(Pr2C6H3)-Pr-i) can be readily prepared from lithium bis(3,5-di-tertbutylpyrazol-1-yl)methide and the N-methyleneaniline H2C=NAr. This NN,N'-heteroscorpionate lithium reagent can be transmetalated with TI(OTf), FeCl2(THF)(1.5), and CoCl2 to yield the (L)TI, (L)FeCl, and (L)CoCl complexes, respectively. Single crystal structural data for compounds (L)Li(THF), (L)TI, (L)FeCl, and (L)CoCl reveal in each case the hapticity of the sterically demanding, monoanionic L- ligand to be kappa(3)-N-3.
