| Abstract
| - Reactions of MCl5 (M = Nb, Ta) with 5 equiv of LiNMe2 have been found to yield, in addition to M(NMe2)5, M(NMe2)4(η2-MeNCH2NMe2) (5-10% yields based on MCl5) containing a chelating ligand (dimethylaminomethylene)methylamide, as confirmed by NMR spectroscopy, DFT calculations, and reactivity studies.
- Reactions of MCl5 (M = Nb, Ta) with LiNMe2 have been found to yield M(NMe2)4(η2-MeNCH2NMe2) (M = Nb, 2a; Ta, 2b) containing a chelating ligand (dimethylaminomethylene)methylamide, as confirmed by NMR spectroscopy, DFT calculations, and their reactivity studies.
