148 words < 350 words) Background: Pest insects are increasingly resistant to phosphine gas, which is used globally to protect grain reserves. The enzyme dihydrolipoamide dehydrogenase (DLD) is a phosphine resistance factor and participates in four key steps of core metabolism, making it a potential central metabolic regulator. Results: Here we used microarray data and NMR-based metabolomics to...

Fumigation with phosphine gas is by far the most widely used treatment for the protection of stored grain against insect pests. The development of high-level resistance in insects now threatens its continued use. As there is no suitable chemical to replace phosphine, it is essential to understand the mechanisms of phosphine toxicity to increase the effectiveness of resistance management. Becaus...

The alkoxycarbonylation of trimethylsilylacetylene has been studied in order to develop an atom economic sustainable synthesis 2‐(trimethylsilyl)acrylates, a family valuable intermediates. Pd(OAc) 2 combination with CH 3 SO H and diphenyl‐(pyridin‐2‐yl)phosphine or diphenyl‐(6‐methyl‐pyridin‐2‐yl)phosphine is active catalyst for the reaction affording mixtures sought 2‐(trimethylsilyl)acrylate ...

this paper presents density functional theory and non-equilibrium green’s function based first principles calculations to explore the sensing property of adenine and thymine based hetero-junction chins for ammonia and phosphine gas molecules. this modeling and simulation technique plays an important and crucial role in the fast growing semiconductor based nanotechnology field. the hetero-juncti...

Facile, metal-mediated, (acceptorless) dehydrogenation of tricyclopentyl phosphine directly affords rhodium chelating phosphine-olefin complexes, some of which are catalytically active for 1,4-additions.

Bis-phosphine oxides can be selectively reduced to bis-phosphine monoxides under exceptionally mild conditions using triflic anhydride and a thiol.

The labile sulfur of adrenodoxin was attacked by a nucleophile, triphenyl phosphine. The product was triphenyl phosphine sulfide regardless of the presence of 02. The stoichiometry between labile sulfur which disappeared and triphenyl phosphine sulfide formed was found to be 1: 1. The initial rate of the reaction follows second order kinetics with a rate constant of 2 to 3 X lo3 M-l mind1 at 38...

background: the poisoning is mostly due to suicide and is observed in younger age groups. the systemic manifestations of alp poisoning are common but pernicious manifestations of them are cardiotoxicity, shock, and ards. the clinical hallmark of cardiotoxicity is arrhythmia. the aim of this study was to investigate cardiac arrhythmias in patients poisoned with alp who were admitted to razi hosp...

The synthesis of InP nanofibers via a new Ullmann-type reaction of indium nanoparticles with tri(m-tolyl)phosphine (P(PhMe)(3)) was typically performed to illustrate an alternative route for the preparation of nanostructured metal phosphides, including III-V (13-15) and transition-metal phosphides. Triarlyphosphine compounds such as other two tri(m-tolyl)phosphine isomers, diphenyl(p-tolyl)phos...

Multifunctional chiral phosphine (phosphine-thiourea type) L2-catalyzed allylic substitutions of MBH adducts 1 with oxazolones 2 produce the corresponding optically active adducts 3 in good to excellent yields and ee's as well as moderate to good de's under mild conditions. The synergistic interaction between hydrogen bond donor site and nucleophilic site has been discussed, indicating that fin...
