When hydroxypteridines are considered, it must be borne in mind that these compounds exist principally in the pteridinone forms, containing thermodynamically stable amide functions, and consequently have low reactivity. Their stability towards acid and alkali correlates well with the number of electron-donating groups which apparently redress the deficit of ir-electrons located at the ring nitrogen atoms. Quantitative correlations can be seen in the decomposition studies of various pteridinones (Table 7). These results are consistent with the number of the oxy functions and their site at the pteridine nucleus. The... 

This enhanced reactivity of fluoromethyl cyanide is undoubtedly due to the inductive effect of the fluorine atom which produces an electron deficit on the carbon atom linked to the nitrogen, and presumably increases still further the polarity of the carbon-nitrogen bond, so that the electron displacements can be pictured as (IX). The increased polarity of the carbon-nitrogen bond will obviously facilitate polar addition of hydrogen chloride and alcohols (or phenols). 

In l,l,l,3,3,3-hexafluoropropan-2-ol, the reaction of l,4-dimethoxy-2,3-dimethylbenzene with a deficit of nitrogen dioxide gives a high concentration of the aromatic cation-radical, which lives long enough and can be detected spectroscopically. In the presence of excessive amounts of N02, this cation-radical decays rapidly giving the 5-nitro derivative of the starting compound (Eberson etal. 1996). 

Laboratory tests indicated for the ongoing monitoring of shock include electrolytes and renal function tests (blood urea nitrogen, serum creatinine) complete blood count to assess possible infection, 02-carrying capacity of the blood, and ongoing bleeding PT and aPTT to assess clotting ability and lactate concentration and base deficit to detect inadequate tissue perfusion. 

Because of the high electron deficit at the two-coordinate phosphorus atom, phosphenium cations are only stable with electron-donating substituents R, predominantly with nitrogen donor atoms. This is an obvious parallel to the situation with stable carbenes of the Wanzlick-Arduengo type. Therefore most complexes in this series are derived from diazaphospholes (75a,...
