Phosphine-Catalyzed (4 + 2) Annulation of Sulfonamido-Substituted Enones with 1,1-Dicyanoalkenes: Synthesis of Piperidine Derivatives

open access: yes, 2021
The δ-sulfonamido-substituted enones were employed as phosphine acceptor in phosphine-catalyzed (4 + 2) annulation of 1,1-dicyanoalkenes. They served as a four-membered synthon to react with 1,1-dicyanoalkenes under mild reaction conditions, producing ...

Gas-Liquid Chromatography and Flame Photometric Detection of Phosphine in Wheat

open access: yesJournal of AOAC INTERNATIONAL, 1978
Abstract A screening method using gas-liquid chromatography with flame photometric detection has been developed for determining phosphine in wheat. Phosphine is measured as the sum of physically bound intact phosphine and that derived from residual aluminum phosphide.

SYNTHESIS OF 1,4-BENZODIAZEPINE THROUGH PHOTOCHEMICAL REACTION OF 3-PHENYL-3,6-DIHYDRO-[1,2]DIOXINE WITH ETHYLENDIAMINE

open access: yesChimica Didactica Acta, 2013
Synthesis of 1,4-Benzodiazepine via reaction of ethylendiamine with 3-phenyl-1,2-dioxine has been carried out. The first step of this experiment was conversion of triphenyl phosphine to triphenyl metyl phosphine iodide which was then used to form phenyl ...

Successful management of zinc phosphide poisoning: possible benefit of virgin olive oil

open access: yesMedicine Science, 2017
Metal phosphides in general and zinc phosphide in particular are potent insecticides and rodenticides. These are commercially used for protection of crops during storage, as well as during transportation. However, these are highly toxic substances.

Stoichiometric and Catalytic Solid–Gas Reactivity of Rhodium Bis-phosphine Complexes

open access: yesOrganometallics, 2015
The complexes [Rh(iBu2PCH2CH2PiBu2)L2][BArF4] [L2 = C4H6, (C2H4)2, (CO)2, (NH3)2; ArF = 3,5-C6H3(CF3)2] have been synthesized by solid−gas reactivity via ligand exchange reactions with, in some cases, crystallinity retained through single-crystal to single-crystal transformations.

Antidotes for aluminum phosphide poisoning – An update

open access: yesToxicology Reports, 2018
Aluminum phosphide (AlP), an inexpensive solid fumigant, is frequently used for grain conservation despite its alleged high toxicity. Increased utilization of AlP for agricultural and non-agricultural purposes during the last four decades has resulted in

Physiological and sanitary performance of soybean seeds during storage after phosphine fumigation

open access: yesJournal of Seed Science
: To maintain the physical, physiological and sanitary qualities of soybean seeds during storage, efficient control of pests must be considered. Fumigation is a technique used to eliminate pests that infest stored seeds, but there is no information on ...

G6PD deficiency might offer protection against fatal poisoning caused by Aluminum phosphide: A Case Series in North Iran [PDF]

open access: yesAsia Pacific Journal of Medical Toxicology
Introduction: Aluminum phosphide (AlP) is a highly toxic pesticide with a high mortality rate due to the lack of a specific antidote. Its toxicity is primarily mediated through the generation of phosphine gas, leading to severe oxidative stress ...
