Studies of stable non-luminescent products

The early work paid relatively little attention to the reactions of radicals produced from the reaction 

Detailed quantitative results for studies of the disproportionation/ dimerization ratio of ethyl and isopropyl radicals are given in Table 9. These sodium flame results suggest that the disproportionation reactions

Gowenlock and co-workers have shown that the n-heptyl bromide/ sodium reaction leads to cyclohexane [115] whereas the perfluoroheptyl iodide/sodium system does not lead to perfluorocyclohexane [116].
