characterization of Ru(II) and V(III) 4,5-diazafluorene derivatives, and their respective reactivity towards B–H bonds. A Ru(II) hydride dinitrogen complex reacts with HBpin to liberate the labile N2 ligand resulting in a dihydridoborate complex. Upon addition of either further HBpin or ClBpin a ligand-based borylation occurs. The first trialkylhydridoborate complex of vanadium was prepared by the addition

The dimeric head-to-tail macrocycles [Cp*Ru(LpH)]2Cl2 (4) and [Cp*RuLp]2 (5) were obtained with the ditopic LpH and Lp– ligands (where LpH = 9-(2-(diphenylphosphino)ethyl)-4,5-diazafluorene and Lp– = 9-(2-(diphenylphosphino)ethyl)-4,5-diazafluorenide). The bulky arene-substituted LMesH ligand (where LMesH = 3,6-dimesityl-4,5-diazafluorene) was prepared, and its coordination to RuCp*}+ gave

The syntheses and structures for a series of heterodinuclear complexes of 4,5-diazafluorenyl (Lâ) and 3,6-dimesityl-4,5-diazafluorenyl (LMesâ) ligands are reported herein. In all these heterodinuclear complexes, the RuII centre is sandwiched between a pentamethylcyclopentadienyl (Cp*) ligand and the C5 ring of Lâ or LMesâ in a double η5 fashion, while the other metal (FeII, CoII, PtII, or CuI) is bound to the N-donors.
