Hypothetical strain-free oligoradicals

Proc Natl Acad Sci U S A. 1980 Oct;77(10):5588-92. doi: 10.1073/pnas.77.10.5588.

Abstract

Several new classes of oligoradicals free of angle strain are suggested and examined by means of molecular orbital calculations. The collapse products of these hypothetical radicals are highly strained molecules. Various electronic strategies for the stabilization of these oligoradicals have been explored.
