Trovacene (1) was prepared by two novel procedures, employing readily available vanadium precursors and after dimetalation converted into the [2]boratrovacenophane 2 [1]boratrovacenophane 4. The reactivity of boron−boron bond in toward [Pt(PEt3)4] studied afforded oxidative addition product 3. X-ray crystallographic studies on 2−4 revealed mutual tiltings carbocyclic rings 11.4, 4.98, 28.23°, respectively.
