Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Facile and Low-Cost SPE Modification Towards Ultra-Sensitive Organophosphorus and Carbamate Pesticide Detection in Olive Oil

Molecules, 2020
Despite the fact that a considerable amount of effort has been invested in the development of biosensors for the detection of pesticides, there is still a lack of a simple and low-cost platform that can reliably and sensitively detect their presence in ...

Photolytic Hydrophosphination: Insights Into Catalyzed and Uncatalyzed Processes

Chemistry – A European Journal, EarlyView.
Catalyst‐free photolytic hydrophosphination is demonstrated for vinyl arenes and activated alkenes in polar protic (alcohol) solvents. These reactions appear to be closed‐shell, affirming that even ambient light can impact a reaction—a potentially broad influence on even mundane reactions.

Zebrafish models for human acute organophosphorus poisoning [PDF]

, 2015
Terrorist use of organophosphorus-based nerve agents and toxic industrial chemicals against civilian populations constitutes a real threat, as demonstrated by the terrorist attacks in Japan in the 1990 s or, even more recently, in the Syrian civil war ...

Engineered Metal–Organic Frameworks‐Based Materials for Environmental Detection

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Engineered metal–organic frameworks (MOFs) regulated by various material modification strategies are discussed for environmental contaminant detection under different sensing mechanisms, providing future improvements of MOFs in environmental detection. Sensitive and selective detection of contaminants is crucial for environmental protection.

Phosphoryl Halogen and Hydrogen Bonding Controls the Solid‐State Structures of Aryl Halide‐Containing Phosphonates

European Journal of Inorganic Chemistry, EarlyView.
Intramolecular (RO)2PO→Halogen interaction versus intermolecular (RO)2PO···HOH hydrogen bonds. Although the O···I distance is shorter than the sum of the van der Waals radii of the atoms involved, there is no covalency involved in this interaction.

Photocatalytic degradation and mineralization of diazinon in aqueous solution using nano-TiO2(Degussa, P25): kinetic and statistical analysis [PDF]

, 2015
: In this study, photocatalytic degradation of diazinon was investigated using nano-TiO2, Degussa P25, as a photocatalyst and the effects of some operational parameters such as aeration, pH, photocatalyst concentration, and the irradiation time were also
