Photoreactions of a series of compounds of the type 9-phenanthryl–A–CH2NHC6H5[–A–=o-phenylene (1b), –(CH2)2– (1c), –(CH2)3– (1d), –(CH2)4– (1e), –CH2– (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 C9, C10-double bond of the phenanthrene ring. These photoproducts can be converted to the starting materials by treating with trifluoroacetic acid or heating above their melting temperatures. The mechanistic features of these reactions are described.
在苯中研究了一系列化合物的光反应,这些化合物的类型为9-联苯基–A–CH2NHC6H5[–A–=邻苯二烯 (1b)、–(CH2)2– (1c)、–(CH2)3– (1d)、–(CH2)4– (1e)、–CH2– (1f)]。从1b–d获得的螺旋化合物是由于N–H功能基团对联苯环C9、C10双键的分子内顺式加成。这些光产物可以通过用 trifluoroacetic acid 处理或加热至其熔点以上,转化为起始材料。本文描述了这些反应的机理特征。
