Group 6 metal complexes with a hemilabile tridentate xantsil ligand and facile insertion of tBuCN into a W-Si bond [xantsil = (9,9-dimethylxanthene-4,5-diyl)bis(dimethylsilyl)].
The synthesis and characterization of tungsten and molybdenum complexes of the xanthene-based bis(silyl) ligand (xantsil) with a kappa3(Si,Si,O) coordination mode are reported, where an insertion of tBuCN into a tungsten-silicon bond leads to formation of an eta2-iminoacyl complex.
