Reactivity of Ru(II) and V(III) complexes of diazafluorene derivatives towards B-H bonds

A Ru(II) hydride dinitrogen complex supported by the 4,5-diazafluorenyl ligand engages in both metal- and ligand-based reactivity with boranes. The reaction of a V(III) trichloride complex supported by a 4,5-diazafluorene derivative with K [HBEt3] yielded the first trialkylhydridoborate complex of vanadium.273
