yield) via intramolecular C-H insertion along with other reaction products. By way of contrast, photodecomposition of 11 afforded a mixture of isomeric azines, 21a–21d, as the major reaction product. No intramolecularcarbene trapping products were obtained when 9 was generated via reaction of 12 with n-BuLi.
