The Living ROMP of trans-Cyclooctene [PDF]
, 2009 The living ring-opening metathesis polymerization (ROMP) of trans-cyclooctene (tCO) was investigated. ROMP of tCO in the presence of PPh_3 in THF leads to the formation of narrowly dispersed polycyclooctene (PCO).

Jurnal Entomologi Indonesia, 2017 Control of postharvest pest on cocoa beans during storage is generally conducted by fumigation with phosphine. Long-term exposure to phosphine and improper fumigation practices could stimulate the development of resistant strains against phosphine.

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

Dates fumigation with phosphine
Julius-Kühn-Archiv, 2018 Stored dates are usually infested by sap beetles and moths. For years, the common practice for dates disinfestation was fumigation with methyl bromide (MB). After MB phase-out, heat treatment and modified atmosphere are used.

Julius-Kühn-Archiv, 2018 Stored product beetles that are resistant to the fumigant phosphine (hydrogen phosphide) have been reported for more than 50 years in many places worldwide. The high levels of phosphine resistance in lesser grain borer Rhyzopertha dominica (F.) have been

Ferrocenyl hydroxymethylphosphines (η⁵-C₅H₅)Fe[η⁵⁻C₅H₄P(CH₂OH)₂] and 1,1′-[Fe{η⁵-C₅H₄P(CH₂OH)₂}₂] and their chalcogenide derivatives [PDF]
, 2002 The ferrocenyl hydroxymethylphosphines FcP(CH₂OH)₂ [Fc=(η⁵-C₅H₅)Fe(η⁵-C₅H₄)] and 1,1′-Fc′[P(CH₂OH)₂]₂ [Fc′=Fe(η⁵⁻C₅H₄)₂] were prepared by reactions of the corresponding primary phosphines FcPH₂ and 1,1′-Fc′(PH₂)₂ with excess aqueous formaldehyde.

Effect of free phosphine on denitrification
浙江大学学报. 农业与生命科学版, 2005 The effect of free phosphine on denitrification was investigated in the batch experiment. It was found that high phosphine concentration (0.50 mL/L and 0.97 mL/L) inhibited the conversion of nitrate when nitrate concentration was low (70 mg/L and 140 mg ...

Phosphine Functionalization of GaAs(111)A Surfaces [PDF]
, 2008 Phosphorus-functionalized GaAs surfaces have been prepared by exposure of Cl-terminated GaAs(111)A surfaces to triethylphosphine (PEt3) or trichlorophosphine (PCl3), or by the direct functionalization of the native-oxide terminated GaAs(111)A surface ...
