Abstract

The synthesis, structure, and photochemical behavior of the trans isomers of 4-(N- phenylamino) stilbene (1c), 4-(N-methyl-N-phenylamino) stilbene (1d), 4-(N, N- diphenylamino) stilbene (1e), and 4-(N-(2, 6-dimethylphenyl) amino) stilbene (1f) are reported and compared to that of 4-aminostilbene (1a) and 4-N, N-dimethylaminostilbene (1b). Results for the corresponding 3-styrylpyridine (2) and 2-styrylnaphthalene analogues ...
