Diaryliodonium salts are versatile arylating agents but generally feature poor atom economy. In this issue of Chem, Olofsson and co-workers describe a novel chemoselective SNAr reaction that sets up second in situ arylation incorporates the iodoarene component cascade with excellent The N- O-based functionalities, producing diarylamine ether structures essential to many biologically active mole...

Let G be a connected, simply simple, complex, linear algebraic group. P an arbitrary parabolic subgroup of G. X=G/P the G-homogeneous projective space attached to this situation. We consider (small) quantum cohomology ring (QH*(X),⋆) X. Postnikov proved that any product two Schubert classes admits unique minimal degree. In particular, result implies there exists degree d which is with property ...

electrochemical impedance spectroscopy (eis) is a suitable and powerful diagnostic testing method for fuel cells (fcs) since it is non-destructive and provides useful information about fc performance and its components. in this study, for the first time, a 500w cascade type 4 cells stack with integrated humidifier, water separator and internal manifolds was designed, fabricated and tested. the ...
