A novel bulky bis(4,6-tBu-benzoxazol-2-yl)methane ligand was synthesized in a straightforward three-step synthesis. The corresponding complexes [Li{(4,6-tBu-NCOC6H2)2CH}THF], [K{η5-(4,6-tBu-NCOC6H2)2CH}]∞, and [MgCl{(4,6-tBu-NCOC6H2)2CH}(THF)2] were obtained upon metalation with alkaline or alkaline-earth-metal reagents. Reduction of [MgCl{(4,6-tBu-NCOC6H2)2CH}(THF)2] with potassium metal or KC8 led to the formation of the homoleptic compound [Mg{(4,6-tBu-NCOC6H2)2CH}2]. All compounds were fully characterized. Their solid-state structures as well as their behavior in solution, which was analyzed with the help of advanced NMR spectroscopic techniques, are discussed in detail. NacNac mimic: Metalation of the methylene bridging moiety in a novel bulky bis(4,6-tBu-benzoxazol-2-yl)methanide ligand with s-block organometallic reagents gave the corresponding N,N-chelated metal salts. Structural features in the solid state (see figure) and in solution were compared to related complexes derived from the ubiquitous NacNac ligand.
