Dimeric benzothiophene-based palladacycles were synthesized from thioanisole-substituted perfluoroalkyl propargyl imines and palladium(II) salts via an intramolecular thiopalladation pathway. The treatment of benzothiophene-based palladacycles with an excess of phosphine ligands in benzene at room temperature selectively afforded trans-bis(phosphine) palladium complexes in good yields. The tran...

In the title 1:1 silver(I) 4-carb-oxy-pyridine-3-carboxyl-ate adduct with triphenyl-phosphine, [Ag(C(7)H(4)NO(4))(C(18)H(15)P)](n), the carboxyl-ate anion bridges the phosphine-coordinated Ag atoms through its N and O atoms, generating a coordination polymer forming layers in the bc plane. The Ag atom exists in a distorted tetra-hedral geometry. The H atom of the carboxyl-ate is midway between ...

In the title triangulo-triruthenium(0) compound, [Ru(3)(C(25)H(22)As(2))(C(6)H(12)Cl(3)O(3)P)(CO)(9)], the bis-(diphenyl-arsino)methane ligand bridges an Ru-Ru bond and the monodentate phosphine ligand bonds to the third Ru atom. Both the arsine and phosphine ligands are equatorial with respect to the Ru(3) triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbon...

Reactions of Cp*Ta(NAr)Cl2 and CpM(NAr)Cl2 (M = Nb, Ta; Ar = 2,6-C6H3(i)Pr2) with NaBH4 in the presence of an excess of PMe3 provided facile access to the corresponding dihydride derivatives Cp(R)M(NAr)H2(PMe3) (Cp(R) = Cp, Cp*). Reaction of Cp*Nb(NAr)Cl2 with NaBH4 in the absence of phosphine gave the Nb(+5) borohydride-hydride complex Cp*Nb(NAr)H(η(2)-BH4). When the corresponding reactions fo...

Reactions of Et3P adducts of bissilylated germylenes and stannylenes with gold, silver, and copper cyanides led to cyanogermyl or -stannyl complexes of the respective metals. In the course of the reaction the phosphine moved to the metal, while the cyanide migrated to the low-coordinate group 14 element. The respective gold complexes were found to be monomeric, whereas the silver and copper com...

Zinc phosphide has been used widely as a rodenticide. Upon ingestion, it gets converted to phosphine gas in the body, which is subsequently absorbed into the bloodstream through the stomach and the intestines and gets captured by the liver and the lungs. Phosphine gas produces various metabolic and nonmetabolic toxic effects. Clinical symptoms are circulatory collapse, hypotension, shock sympto...

The parent benzophospholo[3,2-b]indole was prepared by the reaction of dichlorophenylphosphine with a dilithium intermediate, which was prepared in two steps from 2-ethynyl-N,N-dimethylaniline. Using the obtained benzophosphole-fused indole as a common starting material, simple modifications were carried out at the phosphorus center of the phosphole, synthesizing various functionalized analogs....

Recommended methods for disposal of aluminium phosphide may involve burial. A range of aluminium phosphide preparations used for fumigation consisting of partially spent, and unspent commercial phosphine (PH3) generating aluminium phosphide formulations (blankets and sachets, pellets, and tablets), was buried for 19 months. Phosphine produced by the formulations during this period was monitored...

In the crystal structure of {[Ag(C(6)H(4)NO(2))(C(18)H(15)P)]·C(2)H(6)O}(n), the 4-pyridylcarboxyl-ate ion binds to the phosphine-coordinated silver atoms through one of the two oxygen atoms of the carboxyl unit, and to a third phosphine-coordinate silver atom through the nitro-gen atom of the aromatic ring, giving a distorted tetra-hedral coordination at the metal atom. The μ(3)-bridging mode ...

The title compound, C(30)H(27)O(8)P (1), was formed as one of two products {(1) and (2) [Krawczyk et al. (2010 ▶). Acta Cryst. E66 (cv2753)]} in the reaction of dimethyl acetyl-enedicarboxyl-ate with triphenyl-phosphine. The mol-ecule of (1) consists of a five-membered ring, in which the P atom is incorporated. One of the phenyl groups of the triphenyl-phosphine migrated to a vicinal C atom dur...
