Phosphine distribution during fumigation of wheat in steel bins: extended abstract
Julius-Kühn-Archiv, 2018 Phosphine is a widely used fumigant for controlling insects in stored grain, but fumigation effectiveness is often compromised by suboptimal distribution of the gas.

Sublethal exposure to phosphine decreases offspring production in strongly phosphine resistant female red flour beetles, Tribolium castaneum (Herbst). [PDF]
PLoS ONE, 2012 The red flour beetle is a cosmopolitan pest of stored grain and stored grain products. The pest has developed resistance to phosphine, the primary chemical used for its control.

Ruthenium-Based Heterocyclic Carbene-Coordinated Olefin Metathesis Catalysts [PDF]
, 2010 The fascinating story of olefin (or alkene) metathesis (eq 1) began almost five decades ago, when Anderson and Merckling reported the first carbon-carbon double-bond rearrangement reaction in the titanium-catalyzed polymerization of norbornene.

Application of phosphine fumigant for controlling rice storage insect pests in foundation seeds
Julius-Kühn-Archiv, 2018 The development of phosphine resistance in storage insect pests is now problematic, so the increase of rate and frequency of phosphine fumigation in a storage room is needed.

Effect of free phosphine on sulfate reduction
浙江大学学报. 农业与生命科学版, 2008 The effects of free phosphine on growth and metabolism of sulfate-reducing bacteria were investigated using batch experiment. The results show that when COD/SO42- ratio was 1.0, high phosphine level had an adverse effect on sulfate reduction.

Phosphonate–Phosphinate Rearrangement
The Journal of Organic Chemistry, 2015 LiTMP metalated dimethyl N-Boc-phosphoramidates derived from 1-phenylethylamine and 1,2,3,4-tetrahydronaphthalen-1-ylamine highly selectively at the CH3O group to generate short-lived oxymethyllithiums. These isomerized to diastereomeric hydroxymethylphosphonamidates (phosphate–phosphonate rearrangement).

Phosphine as a Biosignature Gas in Exoplanet Atmospheres [PDF]
Astrobiology, 2019 A long-term goal of exoplanet studies is the identification and detection of biosignature gases. Beyond the most discussed biosignature gas O2, only a handful of gases have been considered in detail. In this study, we evaluate phosphine (PH3).

New Phosphine Oxides as High Performance Near- UV Type I Photoinitiators of Radical Polymerization
Molecules, 2020 Carbazole structures are of high interest in photopolymerization due to their enhanced light absorption properties in the near-UV or even visible ranges.
