Objective: The objective of the study was to report the toxicity of phosphine gas after a residential fumigation that resulted in fatal poisoning of a 15-month-old toddler and her 4-year-old sibling.
Methods: This is a case report and a review of literature.
Results: A family of 6 members was exposed to phosphine gas after their yard was treated with aluminum phosphide for a rodent infestation. The inhalation of phosphine gas initially caused symptoms of abdominal distress in all of the family members. Within 36 hours of exposure, the 4-year-old sibling died of cardiopulmonary failure in a local emergency department. After an initial presentation of respiratory distress, the 15-month-old toddler progressed to complete cardiopulmonary collapse and did not survive despite aggressive intervention including extracorporeal membrane life support.
Conclusions: Unintentional phosphine gas exposure is rare but has a toxic profile that results in a high fatality rate with no known antidote.

Introduction: Aluminum phosphide is a cheap and commonly used rodenticide that is also an effective solid fumigant and frequently used for grain preservation. The pill contains around 44% inert elements (ammonium carbonate) to avoid disintegration of the tablet, while the rest (about 56%) is aluminum phosphide. Because it is freely available on the market, it is one of the commonly used agents for self-poisoning in different parts of the developing world.

The carbonylative polymerization of olefin yields aliphatic polyketones, which are used as engineering plastics in the market due to their excellent mechanical strength, chemical resistance, and surface and barrier properties. However, the usage of precious palladium catalysts has restricted their extensive application as commodity materials. Herein, we present a series of phosphine-sulfonate Ni catalysts with a wide spectrum of electronic and steric substituents on the phosphorus moiety for the carbonylative polymerization of ethylene.

During storage, infestation by insect pests occurs, causing quantitative and qualitative losses in grains, which requires the control of these insects with phosphine gas. Rice husk has a high phosphine adsorption capacity, influencing the gas concentration during fumigation and potentially leading to inefficient fumigation. Additionally, the high sorption of rice husk results in a higher residue of phosphine in the grain.

In this article, the synthesis of bis(phosphine), -PhPCHC(O)N(H)CHCHPPh- (1) (hereafter referred to as "PNHP" and its anionic form as "PNP") and its group 10 metal chemistry and catalytic studies are described. PNHP (1) on reaction with NiCl(DME) and PdCl(COD) afforded pincer complexes, [MCl{(PNP)κ-,,}] (M = Ni, 2; Pd, 3). A similar reaction of 1 with PtCl(COD) yielded a chelate complex, [PtCl{(PNHP)κ-,}] (4), which on further treatment with LiHMDS produced the 1,2-azaphospholene-phosphine complex, [PtCl(Ph){(-P(Ph)CHCONCHCHPPh-)κ-,}] (5) P-C/P-N bond metathesis.

Insights into the molecular mechanism and factors affecting nitrite-to-NO transformation at transition metal sites are essential for developing sustainable technologies relevant to NO-based therapeutics, waste water treatment, and agriculture. A set of copper(II)-nitrite complexes 1-4 have been isolated employing tridentate pincer-type ligands (L, L, L, L) featuring systematically varied donors. Although the X-ray crystal structures of the copper(II)-nitrite cores in 1-4 are comparable, electrochemical studies on complexes 1-4 reveal that redox properties of these complexes differ due to the changes in the σ-donor abilities of the phenolate/N-heterocycle based donor sites.
