Synthesis and reactions of dimethyltin dithiooxalate: a convenient dithiooxalate transfer reagent

Transition metals induce control of enhanced NLO properties of functionalized organometallic complexes under laser modulations

“…All commercially available reagents were used without further purification. The starting materials, ferrocenylacetylene 32 , cis-[Ru(dppm) 2 Cl 2 ] 33 , cis-[RuCl 2 (PPh 3 ) 2 (4,4′-dimethyl-2,2′-bipyridine)] 34 and RuCl(dppe) η 5 -Cp 35 , (E)-N,N-dibutyl-4-((4-bromophenyl)diazenyl)aniline 5 36 and (E)-N,N-dibutyl-4-((4-ethynylphenyl) diazenyl)aniline 21,37 , 6 were prepared by literature methods.…”

“…Like the parent cis-[RuCl 2 (PPh 3 ) 2 (4,4′-dimethyl-2,2′-bipyridine)] complex 34,51 , 3 has a major absorption band in the 450 − 550 nm range (λmax = 514 nm), that can been attributed to ruthenium-to-bipyridyl MLCT transitions 51 . This broad band is accompanied by a distinct shoulder with an apparent maximum at 400 nm which can be consistent with the absorption bands of the azobenzene chromophore.…”

Dichloro(4,4′-di-tert-butyl-2,2′-bipyridine-κ2N,N)bis(triphenylphosphine-κP)ruthenium(II) dichloromethane solvate

“…The title complex was synthesized by a modification of a literature method (Adams, 2002). To a CH 2 Cl 2 solution (25 ml) of Ru(PPh 3 ) 3 Cl 2 (105 mg, 0.11 mmol) was added one equivalent of t Bu 2 bipy (56 mg, 0.11 mmol).…”

“…It is therefore rather surprising that quite a few studies have been carried out for ruthenium(II) complexes with polypyridine and phosphine ligands (Rogers et al, 2001;Batista et al, 1995). Recently, [Ru(PPh 3 ) 2 (Me 2 bipy)Cl 2 ] (Me 2 bipy = 4,4 0 -dimethyl-2,2 0 -bipyridine) (Adams, 2002), which has trans phosphine ligands and cis terminal Cl atoms, has been found to be a good starting material to react with acetylide to give bipyridyl-ruthenium-acetylide andvinylidene complexes with interesting photocatalytic properties (Adams & Pope, 2004). In this paper, we describe the structural characterization of the title complex as the ruthenium-bipyridyl-phosphine analogue, [RuCl 2 (R 2 bipy)(PPh 3 ) 2 ] (R = H and Me) (Batista et al, 1995;Adams, 2002).…”

Synthesis, characterization and conducting properties of complex salts and heterobimetallic coordination polymers of the cyanodithioimidocarbonato ligand

“…The heterobimetallic complexes in general, including those of chalcogen rich ligands, are of great interest because of their structural diversities, cooperative bimetallic activity, molecular magnetism, electrical conductivity and as initiators for photooxidation reactions [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. One of the important synthetic routes for the heterobimetallic coordination polymers is via the formation of metal complex building blocks called as metalloligands.…”
