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.

Phosphine‐Stabilized Pnictinidenes [PDF]
Chemistry – A European Journal, 2021 AbstractThe reaction of the intramolecular germylene‐phosphine Lewis pair (o‐PPh2)C6H4GeAr* (1) with Group 15 element trichlorides ECl3 (E=P, As, Sb) was investigated. After oxidative addition, the resulting compounds (o‐PPh2)C6H4(Ar*)Ge(Cl)ECl2 (2: E=P, 3: E=As, 4: E=Sb) were reduced by using sodium metal or LiHBEt3.

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).
