Complex Tp*RuH

The hydrido complex Tp RuH(COD) reacts with CO to afford the acyl complex Tp Ru C( = 0)C8Hi3 (C0)2 via intramolecular olefin insertion followed by CO addition and insertion. In contrast, reaction of Tp RuH(COD) with acetonitrile was accompanied by C-H activation of a ligand methyl group and H2 elimination, ultimately producing Tp Ru(NCMe)2 as the final product (Scheme 23). 

These include pyrazolylborates such as Tp RuH(H2)2,31 and diazadiene compounds of RN=CR —CR =NR ligands.32 Nitrido and imido compounds are discussed in Section 18-F-ll there are a few amido complexes known.33... 

Very recently, Theopold et demonstrated that the reaction of [RuH(COD) (NH2NMe2)3]BPh4 with TlTp constitutes an efficient route for obtaining Tp RuH(COD). Interestingly, in this compound the Tp ligand is clearly coordinated in the K -mode, based on both spectroscopic data and an X-ray crystallographic study. Notably, this complex could also be obtained by the reaction of RuHCl(bpzm) (COD) (bpzm = bis(pyrazolyl)methane) with TlTp .
