Progress and Prospect of Control Technology for Stored Grain Pests ——Fumigation Insecticides
Liang you shipin ke-ji, 2022 Phosphine and sulfuryl fluoride are two kinds of fumigation insecticides allowed for use in China and overseas. Phosphine is the “trump card” fumigation insecticide for stored grain, while Sulfuryl fluoride is mainly used as the phosphine resistance ...

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).

Cycloaurated triphenylphosphine-sulfide and –selenide [PDF]
, 2010 The first examples of cycloaurated phosphine sulfides and triphenylphosphine selenide have been synthesised; these complexes are fairly rare examples of gold(III) complexes with potentially reducing sulfur- and selenium-donor ligands.

Synthesis, properties, and some rhodium, iridium, and platinum complexes of a series of bulky m-terphenylphosphine ligands [PDF]
, 2016 A series of sterically demanding aryl phosphine ligands (L) bearing terphenyl substituents, PR2Ar′ (R = hydrocarbyl, Ar′ = 2,6-diarylphenyl radical) has been prepared and characterized. The stability of these ligands towards oxidation in the air has been
