The reaction of chloromethyl thiocyanate with 1-methylimidazole affords the imidazolium salt, 1-thiocyanomethyl-3-methylimidazolium chloride, [C1SCNmim]Cl (1a). Exchange of the chloride anion in 1a by [PF6] ...
12-Metallacrown-3 complexes were formed by self-assembly of organometallic half-sandwich complexes [(π-ligand)MCl2]2 (M = Ru, Rh, Ir) and 3-hydroxy-2-pyridone ligands in the presence of Cs2CO3 as base. Upon mixing of different macrocycles, reversible metal ...
A series of ruthenium, osmium and rhodium complexes utilizing pta, (1,3,5-triaza-7-phosphatricyclo-[3.3.1.1]decane) and pta-Me+, its N-methyl derivative, have been synthesized. Their characterization by 1H and 31P NMR spectroscopy, ESI-MS and single crysta ...
Abstract: The connection of lipophilic gallic acid derivatives at the 5,5¢- or 6,6¢-positions of the rigid 2,6-bis(1-ethyl-benzimidazol-2-yl)pyridine core provides two pro-mesogenic tridentate ligands L10 and L12, whose molecular shapes, anisometries, and ...
In aqueous solutions under mild conditions, Ru(H2O)(6) was reacted with various water-soluble tertiary phosphines. As determined by multinuclear NMR spectroscopy, reactions with the sulfonated arylphosphines L = mtppms, ptppms and mtppts yielded only ...
The synthesis and characterization of several new phosphorus-containing partially lower rim substituted derivatives of 5,11,17,23-tetra(t-butyl) calix(4)arene (1) and 5,11,17,23-tetra(t-octyl)calix(4)arene (II), namely 5,11,17,23-tetra(t-butyl)-25,27-dihyd ...
The synthesis and structural properties of three new hydridorhodium(III) complexes are reported. Hydrogenolysis of the cyclometalated Rh dichloride complexes [RhCl2{(S,S)-benbox(Me2)}] (2a-c; benbox(Me2) = 3,5-dimethyl-2,6-bis[(4-R1-4-R2-4,5-dihydrooxazol- ...
Reaction of the dimer [(η5-C5Me5)RhCl(μ2-Cl)]2 with 2 or 4 equiv of the water-soluble phosphine 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane (pta) affords [Rh(η5-C5Me< ...
The reactivity of the iminodiphosphane C6H4(o-CN)N= PPh2-PPh2, which contains an N=P-P unit, has been investigated. Reaction with small molecules, [viz. H2O/O-2, H2O2, CH3OH, C6H4(o-CN)NH2] and elemental sulfur result in cleavage of the P-P bond to give am ...
In analogy to the authors' successful PX2+ insertion reactions, an AsX2+ insertion route was explored to obtain new arsenic halogen cations. Two new salts were prepd.: AsBr4+[Al(OR)4]-, starting from AsBr3, Br2 and Ag[Al(OR)4], and I2As-PI3+[Al(OR)]4 from ...
