文摘

Amidino-boratabenzenes represent a type of L₃X ligand and can be regarded as the monoanionic analogues of the linked amido-cyclopentadienyl ligands. By employment of this type of ligand, 19 constrained-geometry complexes, including Sc(III), Y(III), Lu(III), Zr(IV), and Cr(III) derivatives, have been successfully prepared, and some of them showed excellent catalytic activity for ethylene polymerization upon activation.
