Abstract
1. The reaction of a-nitroolefins, containing the aryl or the ferrocenyl substituent at the double bend, with cyclooctatetraene dipotassium in THF gives dimers derivatives of propane-ω,ω-dinitronic acids. 2. The distribution of the spin density in the anion-radicals ofα-nitro- and α-cyano-βferrocenylethylenes is characterized as follows: the NO2 group surpasses the ferrocenyl group in the competition for the unpaired electron, and the CN group appears to be comparable with, or even weaker than, the ferrocenyl group.
