The front cover picture, designed by El Kazzouli and co-workers, illustrates the site-selective C5 C7 palladium-catalyzed C-H arylations of 4-azaindazole N-oxide. 1,10-phenanthroline as ligand Pd(OAc)2 catalyst in toluene promoted activation position, while triphenyl phosphine PdCl2 DMA directed arylation at position. This new method allows synthesis C5, C7-diarylated N-oxides well C3, C7-triar...

The asymmetric unit of the title compound, [FeCo(2)(C(5)H(5))(2)(C(3)H(3)S(3))S(C(18)H(15)P)(CO)]CF(3)SO(3), consists of a triangular irondicobalt cluster cation and a trifluoro-methane-sulfonate anion. In the cation, the FeCo(2) triangle is symmetrically capped on one face by an S atom and on the other by a C atom linked to a methyl trithio-carbonate residue that bridges the Fe-C bond. Each Co...

In the mononuclear title complex, [CuI(C(6)H(8)N(2)S)(C(18)H(15)P)(2)], the Cu(I) ion is in a slightly distorted tetra-hedral coordination geometry formed by two P atoms from two triphenyl-phosphane ligands, one S atom from a 4,6-dimethyl-pyrimidine-2(1H)-thione ligand and one iodide ion. There is an intra-molecular N-H⋯I hydrogen bond. In the crystal, π-π stacking inter-actions [centroid-centr...

We report a synthesis method for the construction of quaternary aryl phoshonium salts at ambient temperature. The regiospecific reaction involves the coupling of phosphines with aryl radicals derived from diaryliodonium salts under photoredox conditions.

The dinuclear title complex, [Ag(2)Cl(2)(CH(5)N(3)S)(2)(C(18)H(15)P)(2)], lies across an inversion center. The Ag(I) ion exhibits a slightly distorted tetra-hedral coordination geometry formed by a P atom from a triphenyl-phosphane ligand, two metal-bridging S atoms from thio-semicabazide ligands and one chloride ion. The S atoms bridge two symmetry-related Ag(I) ions, forming a strictly planar...

In the title complex, [AgBr(C3H6N2OS)(C18H15P)2], the Ag(I) ion is in a distorted tetra-hedral geometry coordinated by two P atoms from two triphenyl-phosphane ligands, one S atom of an acetyl-thio-urea ligand and one bromide ligand. There are intra-molecular N-H⋯Br and N-H⋯O hydrogen bonds present. In the crystal, pairs of N-H⋯S hydrogen bonds involving thio-urea groups form inversion dimers. ...

The asymmetric unit of the title triphenyl-phosphine compound, C(19)H(17)OP, consists of two crystallographically independent mol-ecules with similar conformations. One of these two mol-ecules has a whole-mol-ecule disorder over two positions with refined occupancies of 0.753 (3) and 0.247 (3). The dihedral angles between the three benzene rings are 89.69 (7), 76.54 (7) and 86.02 (7)° in the no...

In the title solvated salt, [Ag(C18H15P)4](CF3CO2)·C2H5OH, the Ag(I) atom is coordinated by four P atoms from triphenyl-phosphane ligands in a distorted tetra-hedral geometry. The anion and solvent are engaged in weak O-H⋯O hydrogen bonds. Of the four triphenyl-phosphane ligands, two each have an equally disordered phenyl ring while the Ag(I) atom is disordered over two positions in a 0.9595 (1...

In the title compound, [CoRu(C(17)H(14)P)(2)ClH(C(18)H(15)P)(CO)]PF(6)·2CH(2)Cl(2), the Ru(II) atom is coordinated by three P atoms from a chelating 1,1'-bis-(diphenyl-phosphan-yl)cobaltocenium ligand and a triphenyl-phosphine ligand, one CO ligand, one Cl atom and one H atom in a distorted octa-hedral geometry. In the cobaltocenium unit, the two cyclo-penta-dienyl rings are almost parallel, ma...
