Photochemistry of alkyl halides. 4. 1-Norbornyl, 1-norbornylmethyl, 1- and 2-adamantyl, and 1-octyl bromides and iodides

摘要: Competing ionic and radical photobehavior has been observed for a number of alkyl halides. The proportion nucleophilic substitution reduction products were reported each halide. Solvent effects ethylene glycol, triethylamine, methanol atmospheric nitrogen, oxygen, air studied. effect irradiation the halides with methanol-O-d was reported. results discussed in terms initial homolytic cleavage carbon-halogen bond to afford pair, which undergoes competing diffusion hydrogen abstraction give electron transfer an ion pair. turn, gives rise elimination products.
