Y. Iwano et al., PHOTOSENSITIZED ELECTRON-TRANSFER REACTION OF 3-ARYL-2-METHYLOXAZIRIDINE - DIRECT DEOXYGENATION FROM THE ISOMERIC ARYLNITRONE, Bulletin of the Chemical Society of Japan, 67(8), 1994, pp. 2348-2350
Photosensitized electron-transfer reactions of 3-aryl-2-methyloxazirid
ines gave mainly the corresponding benzaldehydes, whereas the isomeric
nitrones gave imines as well as aldehydes. Deoxygenation of the nitro
ne occurred via the nitron cation radical under the reaction condition
s. An aryl substituent effect on the reaction and isomerizations of bo
th cation radicals are also discussed.
