摘要

Photoreactions of a series of compounds of the type 9-phenanthryl–A–CH 2 NHC 6 H 5 [–A– = o-phenylene (1b),–(CH 2) 2–(1c),–(CH 2) 3–(1d),–(CH 2) 4–(1e),–CH 2–(1f)] in benzene were studied. From 1b–d, the spiro compounds are obtained by an intramolecular cis- addition of the N–H function to the C 9, C 10-double bond of the phenanthrene ring. These photoproducts can be converted to the starting materials by treating with trifluoroacetic ...
