CRISTAL-ITE: a single-crystal X-ray diffractometer scale model for scientific dissemination
Autor: Michel Giorgi, Yves Berchadsky
Publikováno v: Journal of Applied Crystallography. 55:149-153
This article presents the design and manufacture of an automated scale model of a four-circle single-crystal X-ray diffractometer that can be used for scientific dissemination. The purpose of this device is to reach out to the wider public and studen

Autor: Jean-Pierre Finet, Christiane Bernard-Henriet, Sylvain R. A. Marque, Robert Lauricella, Paul Tordo, Yves Berchadsky
Publikováno v: Chemistry - A European Journal. 12:7084-7094
Persistent noncyclic phosphoranyl radicals have been prepared and observed by electron paramagnetic resonance (EPR) for the first time. They were obtained by UV-photolysis of a solution containing a bis(trialkylsilyl) peroxide (R = Me, Et) and a tris

Publikováno v: The Journal of Physical Chemistry A. 107:9652-9657
Radical additions of tert-butoxyl radical and alkylthiyl radicals to 2-[(2,4,6-tri-tert-butyl)phenyl]-1-phosphaalkyne have been investigated by ESR. The addition of oxygen or sulfur centered radical leads to an intermediate phosphavinyl σ-radical, w

Complementary cardioprotective effects of flavonoid metabolites and terpenoid constituents of Ginkgo biloba extract (EGb 761) during ischemia and reperfusion
Autor: Thibaut Liebgott, Katy Drieu, Sylvia Pietri, Yves Berchadsky, Malvina Miollan, Marcel Culcasi
Publikováno v: Basic Research in Cardiology. 95:368-377
Hemodynamic and electron spin resonance (ESR) analyses were performed on isolated ischemic and reperfused rat hearts to assess the cardioprotective and antioxidant effects of therapeutically relevant concentrations of Ginkgo biloba extract (EGb 761;

Trimesityl phosphoniumyl cation radical: electrogeneration and evolution
Autor: Belabbes Merzougui, Gérard Gronchi, Paul Tordo, Yves Berchadsky
Publikováno v: Electrochimica Acta. 42:2445-2453
The electrochemical oxidation of tris (2,4,6-tri-methyl-phenyl) phosphine (TMP) in acetonitrile was investigated on a platinum electrode. A fast mono-electronic transfer ( E p = 0.71 V vs sce ) gives rise to the corresponding long-lived phosphoniumyl

β-Phosphorylated five membered ring nitroxides, a new class of stable nitroxides. 1. Synthesis by Reaction. of dialkylphosphites with 1-pyrroline-n-oxides
Autor: Pietri Sylvia, Anne Mercier, Paul Tordo, Badrudin, Yves Berchadsky
Publikováno v: Tetrahedron Letters. 32:2125-2128
Dialkylphosphites add to 2,5,5-trialkyl-1-pyrroline-N-oxides to give, after oxidation with copper(II)acetate, the corresponding β-phosphorylated nitroxides, which are stable in many organic solvents.

Anodic behavior of crowded triarylphosphines. ESR study of triarylphosphoniumyl radicals, Ar3P.bul.+
Autor: Marcel Culcasi, Yves Berchadsky, Gerard Gronchi, Paul Tordo
Publikováno v: The Journal of Organic Chemistry. 56:3537-3542
A large number of triarylphosphines exhibiting different steric hindrance has been prepared. The pyramidalization angle α of these compounds was calculated with use of the MM2 force field and was shown to depend almost exclusively on the number of o
