P-stereogenic centre via Pd/Cu-bimetallic catalytic selective phosphinylation of allenylic acetates [PDF]
P-stereogenic organophosphorus compounds are a class of highly important compounds due to their potentials in asymmetric catalysis both as ligands or catalysts and medicinal chemistry. Herein, we report an efficient protocol under bimetallic catalysis of

Chemistry, Metabolism and Neurotoxicity of Organophosphorus Insecticides: A Review [PDF]
Organophosphorus compounds (OPs) are phosphoric acid derivatives represented by the formula (R2XP=O/S), R as organic groups; however, they need not contain a direct carbon-phosphorus bond.

From Mechanisms to Materials: Oximate Reactivity and Emerging Strategies for Organophosphate Detoxification. [PDF]
The development of effective strategies for the detoxification of organophosphorus (OP) nerve agents has evolved from the early mechanistic studies of François Terrier and collaborators, who first elucidated the exceptional nucleophilicity of α‐effect species such as oximes and hydroxamates, to the modern design of supramolecular and material‐based ...

Chemical Weapons: History of the Study of Organophosphorus Toxic Agents Abroad
Organophosphorus compounds occupy a unique positon among all chemical warfare agents (CWA's). Since the 1930-s their high toxicity, wide range of physical-chemical properties and complex action attracted close attention of foreign military experts.

Asymmetrically Substituted Phospholes as Ligands for Coinage Metal Complexes
A series of coinage metal complexes asymmetrically substituted 2,5-diaryl phosphole ligands is reported. Structure, identity, and purity of all obtained complexes were corroborated with state-of-the-art techniques (multinuclear NMR, mass spectrometry ...
