โœฆ Synopsis

The photochemical behavior of cis-1,2-dihydrophthalide (l_) and its 1,2-trim-ethylene derivative (4_) was studied. Besides blcyclo[2.2.0]hexene formation in both cases, (1) transforms into its trans isomer (3 whereas (4_) undergoes a 1,2-shift to (7).

The photolysis of 1-aryloxy-2-azidoanthraquinones (3) in benzene is described herein which gave 1-hydroxy-2-arylaminoanthraquinones (4) and two types of 5H-naphtho[2,3-c]phenoxazine-8,13-diones (5 and 6). Thermolysis of 3 yielded only one of phenoxazines 5 and small amount of 4. On the other hand th
