The Mitsunobu reaction is renowned for its mild reaction conditions and broad substrate tolerance, but has limited utility in process chemistry and industrial applications due to poor atom economy and the generation of stoichiometric phosphine oxide and hydrazine by-products that complicate purification. A catalytic Mitsunobu reaction using innocuous reagents to recycle these by-products would ...

The title compound, [Ru(C(10)H(15))Cl(C(12)H(10)ClP)(C(17)H(20)NP)], is a half-sandwich complex of Ru(II) with the chloro-diphenyl-phosphine ligand formed from the diphenyl-piperidinophosphine and chlorine of the precursor complex [Ru(η(5)-C(5)Me(5))(κ(1)P-Ph(2)PNC(5)H(10))Cl(2)] by an unexpected reaction with NaBH(4). The complex has a three-legged piano-stool geometry, with Ru-P bond lengths ...

Phosphine-based detection strategies for both nitroxyl (HNO) and S-nitrosothiols (RSNO) were investigated and compared. Phosphorus NMR studies show that azaylides derived from HNO or organic RSNO efficiently participate in subsequent reductive ligation required for fluorescence generation in properly substituted substrates. S-Azaylides derived from biological RSNO containing free amine and carb...

The title compound, [Co(C(30)H(23)O(2)P(2))(C(3)H(9)P)(2)], was synthesized by the addition of a Co(PMe(3))(4) solution to (PPh(2)O)(2)C(6)H(4). The Co(I) atom displays a trigonal-bipyramidal geometry with the two P atoms of the 'PCP' pincer ligand and the P atom of one of the trimethyl phosphine ligands forming the basal plane, whereas the metalated C atom and the P atom of the second phospine...

Many pests cause serious economic losses in the carnation cultivation areas Turkey. Western flower thrips, Frankliniella occidentalis Perg. (Thysanoptera: Thripidae) is harmful on by feeding both leaves and flowers listed as a quarantine pest some exporting countries. Due to invasions of western thrips chemical control measures are traditionally used phytosanitary measure for flower cut carnatio...

The resistance to fumigant insecticides in stored-products insects is often recorded. Several factors influence the evolution of insecticide resistance. Among these, the frequency of applications and the migration of resistant populations are of primary importance for the stored-product insects. The aim of this study was to characterize the spectrum and investigate the status of phosphine resis...

The recent emergence of heritable high level resistance to phosphine in stored grain pests is a serious concern among major grain growing countries around the world. Here we describe the genetics of phosphine resistance in the rust red flour beetle Tribolium castaneum (Herbst), a pest of stored grain as well as a genetic model organism. We investigated three field collected strains of T. castan...
