We report a series of [2]borametallocenophanes of Ti, Zr, and Hf with various ligand systems. The ligands have been synthesized in high yields starting from 1,2‐dibromo‐1,2‐bis(dimethylamino)diborane(4) upon reaction with Na[C 5 H 5 ] and Li[C 13 H 9 ], respectively. All compounds were fully characterized by multinuclear NMR spectroscopy and, for selected examples, by X‐ray analysis.
