Abstract
Abstract Tetrakis(diethylamido)zirconium reacts with 2‐(dimethylamino)methyl pyrrole (DMAMP) and 2,5‐[bis(dimethylamino)methyl]pyrrole (BDMAMP) to give Zr(NEt) 2 (DMAMP) 2 1 and Zr(NEt) 3 (BDMAMP) 2 , respectively. Both 1 and 2 have been characterized by 1 H and 13 C NMR spectroscopies and 1 has also been characterized by X‐ray crystallography. Complex 1 shows an agostic interaction between Zr and H(21A) in solid state that is not sustained in solution. Reacting 1 with 2 equivalents of trimethylsilyl chloride in toluene yields ZrCl 2 (DMAMP) 2 3 in 75% yield which was characterized by 1 H and 13 C NMR spectroscopies.
