The monopotassium salt of the ligand of a Ziegler–Natta catalyst
Abstract
The anion of dipotassium (tert-butylamino)-dimethyl(tetramethylcyclopentadienyl)silanediide can coordinate to transition metals to form precursors for single-component Ziegler-Natta polymerization catalysts. The related monoanion derivative potassium (tert-butylamino )dimethyl( tetramethyl-cyclopentadienyl) silanide tetrahydrofuran solvate has been isolated as the first crystalline salt of this important ligand family. The tetramethylcyclopentadienyl group in the crystal has a potassium ion on each face, 2.8 Å from the center of the five-membered ring; each K atom is bonded to two rings and one tetrahydrofuran solvent molecule.
