Stoichiometric and Catalytic Synthesis of Alkynylphosphines

Molecules, 2012
Alkynylphosphines or their borane complexes are available either through C–P bond forming reactions or through modification of the phosphorus or the alkynyl function of various alkynyl phosphorus derivatives.

Effect of aluminium phosphide (ALP) gas inhalation exposure on adipose tissue characteristics and histological toxicity in male rats

Journal of Taibah University for Science, 2020
Considering the increasing incidence of fatal aluminium phosphide (ALP) poisoning and its toxicological aspects and also the paucity of our knowledge concerning the ALP effect on adipose tissue and adipokines, the present study aimed to assess the effect

Green Emissive Copper(I) Coordination Polymer Supported by the Diethylpyridylphosphine Ligand as a Luminescent Sensor for Overheating Processes

Molecules, 2023
Tertiary diethylpyridylphosphine was synthesized by the reaction of pyridylphosphine with bromoethane in a suberbasic medium. The reaction of phosphine with the copper(I) iodide led to the formation of a copper(I) coordination polymer, which, according ...

Intramolecular Phosphine-Promoted Knoevenagel Based Redox-Reaction

Molecules, 2022
A Knoevenagel based redox-reaction promoted by intramolecular phosphine sources is presented for the first time. The influence of different diketones, aldehydes, bases and acids was investigated. The effects of different substituents were evaluated based

Sensing Organophosphorus Compounds with SWCNT Films

Sensors, 2021
Promising electrical properties of single-walled carbon nanotubes (SWCNTs) open a spectrum of applications for this material. As the SWCNT electronic characteristics respond well to the presence of various analytes, this makes them highly sensitive ...

Trivalent Phosphorus and Phosphines as Components of Biochemistry in Anoxic Environments.

Astrobiology, 2019
Phosphorus is an essential element for all life on Earth, yet trivalent phosphorus (e.g., in phosphines) appears to be almost completely absent from biology.

Chiral terpene auxiliaries V: Synthesis of new chiral γ-hydroxyphosphine oxides derived from α-pinene

Beilstein Journal of Organic Chemistry, 2019
New chiral regioisomeric γ-hydroxyphosphine ligands were synthesized from α-pinene. The key transformation was the thermal [2,3]-sigmatropic rearrangement of allyldiphenylphosphinites, obtained from (1R,2R,4S,5R)-3-methyleneneoisoverbanol and (1R,2R,3R ...

Room Temperature Ni(II) Catalyzed Hydrophosphination and Cyclotrimerization of Alkynes

Inorganics, 2018
The catalytic activity of nickel complexes in hydrophosphination involving secondary phosphines is not a commonly studied transformation. Beyond a small number of stand-out examples, many reports in the literature focus on the use of simple nickel salts.
