Conclusions
-
1.
The EPR spectra of the radical anions formed from diphenylmethane, diphenylethane, and diphenylpropane on reduction with metallic potassium under various conditions and at various temperatures have been discussed.
-
2.
The point of view found in the literature that the delocalization of an electron through saturated methylene bridges in compounds of the type considered is possible has arisen on the basis of inaccurate experiment.
