Amidate complexes of group(IV) metals have shown a variety of interesting and useful capabilities. The modular synthesis of the amidate proligand allows for high-tunability. Amidate ligands have been shown to be hemilabile, allowing for varied reactivity at metal centers. A series of L2MoX2 complexes (where L = various amidate ligands, X2 = O2, (NtBu)2, and O/NtBu) have been synthesized and characterized via elemental analysis, 1H NMR spectroscopy, and infrared spectroscopy. Solid state molecular structures have also been determined using X-ray crystallography. Mo(VI) amidate complexes exhibiting hemi-lability will be discussed. Dynamic behavior of the mixed O/NtBu system in solution will be discussed. Reactivity at multiply bonded fragments with various substrates has been explored. In addition, complimentary Mo(VI) complexes with alternative ligands featuring tight bite angles have been explored.
