The photolysis of diazoindene and diazofluorene at 12 K in N2 matrices containing O2 has been studied, using i.r. spectroscopy.The carbonyl oxides, indenone O-oxide and fluorenone O-oxide, were formed by the reaction of O2 with the corresponding carbenes, and under appropriate conditions could be detected as very photolabile species.Photolysis of indenone O-oxide gave indenone and isocoumarin; similar photolysis of fluorenone O-oxide gave fluorenone and dibenzopyran-6-one.
