The concave position of the proton in protonated concave pyridines 8*H+ or 9*H+ leads to increased selectivities in protonation reactions of nitronate anions 2a-d.Thus, the reprotonation of the nitronate anion 2a by the protonated concave pyridine 8*H+ selectively yields the nitro compound 1a whereas the nitronate anions 2b-d are transformed to the Nef products 4b-d.
Electrochemical oxidation of carboxylic acid anions in the presence of some mono- and di-subsituted olefins

The anodic oxidation of the sodium salts of acetic, propionic, and isovaleric acids was performed in the presence of a series of ethylenic compounds bearing electron-withdrawing substituents.The results showed that under certain experimental conditions the electrogenerated radicals added to the ethylenic double bond to give mainly 1,2-dialkylated products.The stereoisomers obtained were separated and whenever possible, identified.Their physical properties are reported.
