XVI. (2,5-C4tBu2RHN)MCl3 (M Ti, Zr, Hf; R H, SiMe3)—Azacyclopentadienyl-Komplexe der Gruppe 4-Metalle
摘要:
The azacyclopentadienyl compounds (2,5-C4tBu2RHN)MCl3 (M = Ti, Zr, Hf; R = H, SiMe3) have been prepared as stable solids from the lithiated pyrroles and MCl4. The pi-coordination of the azacyclopentadienyl ligands, as suggested from C-13 NMR data, has been confirmed for (2,5-C4tBu2H2N)TiCl3 by an X-ray diffraction study.
