Abstract

This paper describes product and flash photolysis studies following irradiation in aqueous solution of 4X–C6H4N3 [X= MeO (12a), EtO (12b), PriO (12c), ButO (12d), C6H5O (12e), 4- MeOC6H4O (12f), F, Cl] and 4-methoxy-1-naphthyl azide (15). p-Benzoquinone (or 1, 4- naphthoquinone) is observed as a product, in yields of 70–90% with 12a–d, 15, 40% with 12e, 26% with 4-F and 15% with 4-Cl. The quinone arises by a pathway whereby the ...
