Abstract: The conversion rate and quantum yield of photosensitized isomerization of dimethyl N-(p-tosyl)-7-aza-bicyclo(2.2.1)-2, 5-heptadiene-2, 3-dicarboxylate, with diphenylguanidine and N-ethylcarbazole as sensitizer, have been measured. The reaction mechanism of electron transfer Is omerization was proposed.

Key words: photosensitization, eletron transfer, isomerization, dimethyl N-(p-tosyl)-7-aza-bicyclo(2.2.1)-2,5-heptadiene-2,3-dicarboxyIate
