- Photochemistry of 1,3-Distyrylbenzene - A New Route to syn-(1,3)Cyclophanes
-
Depending on the reaction conditions the irradiation of the title compound 1 leads to cyclodimerization 1 -> 6, dehydrogenating cyclization 1 -> 11, 12 or a combination of both processes 1 -> 13, 14, 15.The stereoisomeric (1,3)cyclophanes 6a - c as well as the access into the pyrene series 15, 16, 18 are of special synthetic interest.
