12, a dimethylnaphthalene, bibenzyl, and two methylstilbenes were claimed; from the portrayed spectrum, the most prevalent were the minor amounts of toluene and styrene, while the others were trivial compared with αMS. For 1-h runs at increasing T in hydrogen donor solvents in a sealed autoclave (Ref. [16]), a secondary conversion of αMS to cumene and ethylbenzene was clearly demonstrated.

This fraction is based on the suggestion of Ruchardt and Beckhaus (Ref. [67]) that, for series of internally strained molecules, an increase in strain energy decreases E by only ≈2/3 because of the compensation by a growing barrier to recombination.
