Popis:	Irradiation of benzene solutions containing pyrene and electron-deficient arylalkenes such as E - and Z -methyl cinnamates afforded (2π+2π) photocycloadducts including 1:2-cycloadduct in high yields in a stereospecific and endo -selective manner. Sandwich-type singlet exciplexes between pyrene and arylalkenes were proposed as reactive intermediates.
