The ruthenium(II) half-sandwich complex [RuCl(η 5 -C 5 H 5 )(PPh 3 ) 2 ] (1) catalyses the reaction between methanol and alkylamines RNH 2 or R 1 R 2 NH to afford RN(CH 3 ) 2 and R 1 R 2 NCH 3 products, respectively. The reaction is quantitative and generally fast, at the methanol reflux temperature, for a wide spectrum of substrates. Starting from primary amines, the stepwise formation of RN=CH 2 , RNHCH 3 , and

It is recognished that the properties of the metal complexes of phasphorus doner ligands 1,3 are markedly affected by the electronic and steric effects of the substituents on Phasphorus. However, investigations on the electronic and steric effects in metal complexes of arsenic donar ligands have been lacking. Recently reactions of [Ru (η 5-C 5 H 5) (PPh 3) 2 Cl] with source aromatic thioamides (R 1 CSNHCOR 2) have been reported 4. We report here the synthesis and characterisation of the products of [Ru(η 5-C 5 H 5)(PPh 3) 2 X] (X=Cl, Br, I), with

“…In fact, the CpRu fragment, and its Cp*Ru analogue, are recognized as effective catalysts for the promotion of many versatile synthetic transformations [4,5,8–12] . Of importance for the current study, combinations of [CpRu] and nitrogen‐based ligands [1,3,13,14] such as diimines [15–26] were also found to catalyze original processes [7,27,28] . For example, [CpRu(CH 3 CN) 3 ][PF 6 ] and pyridine‐imine/pyridine‐oxazoline ligands are effective catalysts in enantioselective decarboxylative rearrangements of allylic β‐ketoesters and carbonates [26,29–32] .…”

Dedicated to Prof. Antonio Togni on the occasion of his 65th birthday Cationic [Ru(η 5-C 5 H 5)(CH 3 CN) 3 ] + complex, tris(acetonitrile)(cyclopentadienyl)ruthenium(II), gives rise to a very rich organometallic chemistry. Combined with diimine ligands, and 1,10-phenanthroline in particular, this system efficiently catalyzes diazo decomposition processes to generate metal-carbenes which undergo a series of original transformations in the presence of Lewis basic substrates. Herein, syntheses and characterizations of [CpRu(Phen)(L)] complexes with (large) lipophilic non-coordinating (PF 6 À and BAr F À) and coordinating TRISPHAT-N À anions are reported. Complex [CpRu(η 6-naphthalene)][BAr F ] ([1][BAr F ]) is readily accessible, in high yield, by direct counterion exchange between [1][PF 6 ] and sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (NaBAr F) salts. Ligand exchange of [1][BAr F ] in acetonitrile generated stable [Ru(η 5-C 5 H 5)(CH 3 CN) 3 ][BAr F ] ([2][BAr F ]) complex in high yield. Then, the desired [CpRu(Phen)(CH 3 CN)] ([3]) complexes were obtained from either the [1] or [2] complex in the presence of the 1,10-phenanthroline as ligand. For characterization and comparison purposes, the anionic hemilabile ligand TRISPHATÀ N (TTN) was introduced on the ruthenium center, from the complex [3][PF 6 ], to quantitatively generate the desired complex [CpRu(Phen)(TTN)] ([4]) by displacement of the remaining acetonitrile ligand and of the PF 6 À anion. Solid state structures of complexes [1][BAr F ], [2][BAr F ], [3][BAr F ], [3][PF 6 ] and [4] were determined by X-ray diffraction studies and are discussed herein.
