The present study describes the synthesis, characterization, antileishmanial and antiplasmodial activities of novel diimine/(2,2′- bipyridine (bipy), 1,10-phenanthroline (phen), 4,4′-methylbipyridine (Me-bipy) and 4,4′-methoxybipyridine (MeO-bipy)/phosphi

Dimethyltin dithiooxalate has been synthesised by the reaction of dimethyltin dichloride with potassium dithiooxalate. It may be used as a dithiooxalate (dto) transfer reagent, reacting with [PtL2Cl2] (L2 = 1,4-cyclooctadiene or 4,4'-bis(tert-butyl)-2,2'-bipyridine) to eliminate SnMe2Cl2 and form the corresponding platinum dithiooxalate compounds [Pt(COD)(dto)] 1 and [Pt(tBu2bipy)(dto)] 2. Reaction with the ruthenium compound [Ru(Me2bipy)(PPh3)2Cl2] 3 (Me2bipy = 4,4'-dimethyl-2,2'-bipyridine) does not proceed analogously however, eliminating from the ruthenium one chloride and one triphenylphosphine ligand, and thus producing not SnMe2Cl2 but [SnMe2Cl]+ . This moiety becomes chelated within the dithiooxalate to produce the new 'Coucouvanis' type compound [cis-Ru(Me2bipy)(PPh3)Cl(μ-dto)(SnMe2Cl)] 4. Reaction of 4 with DMSO causes the elimination of SnMe2Cl2 by abstracting the tin centre and the second chloride ligand, producing cis-[Ru(Me2bipy)(PPh3)-(DMSO)(dto)] 5. Upon treating 3 with [p-N≡NC6H4F][BF4] the oxidation product [Ru(Me2bipy)(PPh3)2Cl2][BF4 ] 6 is formed. 6 reacts with SnMe2(dto) to produce a second bimetallic complex, [Ru(Me2bipy)(PPh3)2(μ-dto)-(SnMe2 Cl)][BF4] 7a. The nature of the reduction products of 4 and 7 is explored, and the X-ray crystal structures of 2 and 5 are presented.
Electrochemical and spectroscopic studies on RuCl2(PPh3)2(N)2 and RuCl2(PPh3)2(N-N) complexes (N = pyridine derivatives and N-N = phenanthroline or bipyridine derivatives). X-ray structure of RuCl2(PPh3)2(phen)

A series of RuCl2(PPh3)2(N)2 and RuCl2(PPh3)2(N-N) complexes were synthesized from RuCl2(PPh3)3, (N)2 = pyridine (py), 4-(N,N-dimethylamino)pyridine (4-dmNpy), 4-tert-butylpyridine (4-tBu-py), 4-methylpyridine (4-Mepy), 4-vinylpyridine (4-Vpy), 4-phenylpyridine (4-Phpy), isonicotinamide (4-CONH2py), 4-cyanopyridine (4-CNpy) N-N = 1,10-phenanthroline (phen), 2,2′-bipyridine (bipy), 2,2′-bipyridine-4,4′-dimethoxy (MeO-bipy), 2,2′-bipyridine-4,4′-dimethyl (Me-bipy), 2,2′-bipyridine-4,4′dithiomethyl (MeS-bipy), 2,2′-bipyridine-4,4′-dichloro (Cl-bipy) and 2,2′-bipyridine-4,4′-dinitro (NO2-bipy). The complexes were characterized by elemental analysis, cyclic voltammetry and UV-Vis, NMR and IR spectroscopies. The structure of the RuCl2(PPh3)2(phen) was established by single crystal X-ray crystallography.
