Photochemical generation of acetonitrile oxide via the C–N bond cleavage of 3-methyl-2-(4-nitrophenyl)-2H-azirine
Abstract
Acetonitrile oxide (2) is produced by the irradiation of the title azirine 1 in the presence of O2 in fluid solutions and in low-temperature matrices through the capture of the biradical 7 with O2, which is generated by the photochemical C–N bond cleavage of the azirine ring.
