Preferred Label : aromatic photocycloaddition;
IUPAC definition : Inter- and intramolecular i photochemical processes /i involving the addition of
a C–C double (or triple) bond (i) to the 1,2-positions of an arene in which case it
is called an i ortho photocycloaddition /i , with formation of a benzocyclobutene
(or a benzocyclobutadiene) derivative, (ii) to the 1,3-positions of an arene in which
case it is called a i meta photocycloaddition /i , with formation of tricyclo[3.3.0.0
sup 2,8 /sup ]oct-3-ene (or octa-3,6-dien) derivatives, or (iii) to the 1,4-positions
of an arene in which case it is called a i para photocycloaddition /i , with formation
of bicyclo[2,2,2]oct-2-ene (or octa-2,5-dien) derivatives.;
