Photochemical addition reactions of 1,4- and 1,2-quinones with alkylbenzenes or with ethers

  • Alexander Schönberg


According to Moore and Waters [1], chloranil (1) reacts photochemi-cally with p-xylene (2) in a free radical manner to form 2,3,5,6-tetrachloro-4-(4-methylbenzyloxy)-phenol (3). Similar compounds, including 1:2-adducts of 1 with xylene, were obtained in dark reactions when 1 was employed as dehydrogenating agent in the steroid field [2], the formation of the ethers being explained in terms of an ionic reaction mechanism.
